change_protocol_from_now(new_stages, machine=None)[source]¶

Return type:: None

For a running experiment, change the remaining stages to be the provided :param:`new_stages` list. This is a convenience function that:

Gets the currently-running stage and cycle.
Sets the repeat number of the current stage to its current cycle, thus ending it after the end of the current cycle.
Changes the remainder of the stages to be those in the :param:`new_stages` list.

Because this does not impact any current or past stages, there is less of a need to ensure that the stages provided are compatible with the old protocol. The only check done is to ensure that, if the provided stages have any collection commands using default filters, the old protocol has specified default filters. This function does not allow the default filters to be changed: if you want to use filters other than the defaults, or defaults were not provided in the old protocol, then either specify filters explicitly (recommended) for new stages you’d like to be different, or use Experiment.change_protocol directly.

createdtime: datetime¶: The run creation time.

data_for_sample(sample)[source]¶

Convenience function to return data for a specific sample.

Finds wells using self.plate_setup.sample_wells[sample], then returns self.welldata.loc[:, wells]

plot_anneal_melt(samples=None, filters=None, anneal_stages=None, melt_stages=None, between_stages=None, process=None, normalization=None, ax=None, marker=None, legend=True, figure_kw=None, line_kw=None)[source]¶

Plots anneal/melt curves.

This uses solid lines for the anneal, dashed lines for the melt, and dotted lines for anything “between” the anneal and melt (for example, a temperature hold).

Line labels are intended to provide full information when read in combination with the axes title. They will only include information that does not apply to all lines. For example, if every line is from the same filter set, but different samples, then only the sample will be shown. If every line is from the same sample, but different filter sets, then only the filter set will be shown. Wells are shown if a sample has multiple wells.

Parameters:

samples (str | Sequence[str] | None) – A reference to a single sample (a string), a list of sample names, or a Python regular expression as a string, matching sample names (full start-to-end matches only). Well names may also be included, in which case each well will be treated without regard to the sample name that may refer to it. Note this means you cannot give your samples names that correspond with well references. If not provided, all (named) samples will be included.
filters (str | FilterSet | Collection[str | FilterSet] | None) – Optional. A filterset (string or FilterSet) or list of filtersets to include in the plot. Multiple filtersets will be plotted on the same axes. Optional; if None, then all filtersets with data in the experiment will be included.
anneal_stages (int | Sequence[int] | None) – Optional. A stage or list of stages (integers, starting from 1), corresponding to the anneal, melt, and stages between the anneal and melt (if any). Any of these may be None, in which case the function will try to determine the correct values automatically.
melt_stages (int | Sequence[int] | None) – Optional. A stage or list of stages (integers, starting from 1), corresponding to the anneal, melt, and stages between the anneal and melt (if any). Any of these may be None, in which case the function will try to determine the correct values automatically.
between_stages (int | Sequence[int] | None) – Optional. A stage or list of stages (integers, starting from 1), corresponding to the anneal, melt, and stages between the anneal and melt (if any). Any of these may be None, in which case the function will try to determine the correct values automatically.
normalization (Processor | None) – Optional. A Normalizer instance to apply to the data. By default, this is NormRaw, which passes through raw fluorescence values. NormToMeanPerWell also works well.
ax (plt.Axes’ | None) – Optional. An axes to put the plot on. If not provided, the function will create a new figure, by default with constrained_layout=True, though this can be modified with figure_kw.
marker (str | None) – The marker format for data points, or None for no markers (default).
legend (bool | Literal[‘inset’, ‘right’]) – Whether to add a legend. True (default) decides whether to have the legend as an inset or to the right of the axes based on the number of lines. “inset” and “right” specify the positioning. Note that for “right”, you must use some method to adjust the axes positioning: constrained_layout, tight_layout, or manually reducing the axes width are all options.
figure_kw (Mapping[str, Any] | None) – Optional. A dictionary of options passed through as keyword options to the figure creation. Only applies if ax is None.
line_kw (Mapping[str, Any] | None) – Optional. A dictionary of keywords passed to all three plotting commands.

Return type:

plt.Axes

Returns:

plt.Axes – The axes object of the plot.

plot_over_time(samples=None, filters=None, stages=slice(None, None, None), process=None, normalization=None, ax=None, legend=True, temperatures='axes', marker=None, stage_lines=True, annotate_stage_lines=True, annotate_events=True, figure_kw=None, line_kw=None)[source]¶

Plots fluorescence over time, optionally with temperatures over time.

Line labels are intended to provide full information when read in combination with the axes title. They will only include information that does not apply to all lines. For example, if every line is from the same filter set, but different samples, then only the sample will be shown. If every line is from the same sample, but different filter sets, then only the filter set will be shown. Wells are shown if a sample has multiple wells.

Parameters:

samples (str | Sequence[str] | None) – A reference to a single sample (a string), a list of sample names, or a Python regular expression as a string, matching sample names (full start-to-end matches only). Well names may also be included, in which case each well will be treated without regard to the sample name that may refer to it. Note this means you cannot give your samples names that correspond with well references. If not provided, all (named) samples will be included.
filters (str | FilterSet | Collection[str | FilterSet] | None) – Optional. A filterset (string or FilterSet) or list of filtersets to include in the plot. Multiple filtersets will be plotted on the same axes. Optional; if None, then all filtersets with data in the experiment will be included.
stages (slice | int | Sequence[int]) – Optional. A stage, list of stages, or slice (all using integers starting from 1), to include in the plot. By default, all stages are plotted. For example, to plot stage 2, use stages=2; to plot stages 2 and 4, use stages=[2, 4], to plot stages 3 through 15, use stages=slice(3, 16) (Python ranges are exclusive on the end). Note that is a slice, you can use None instead of a number to denote the beginning/end.
normalization (Processor | None) – Optional. A Normalizer instance to apply to the data. By default, this is NormRaw, which passes through raw fluorescence values. NormToMeanPerWell also works well.
temperatures (Literal[False, ‘axes’, ‘inset’, ‘twin’]) –
Optional (default “axes”). Several alternatives for displaying temperatures. “axes” uses a separate axes (created if ax is not provided, otherwise ax must be a list of two axes).

Temperatures are from Experiment.temperature, and are thus the temperatures as recorded during the run, not the set temperatures. Note that this has a very large number of data points, something that should be dealt with at some point.
ax (Axes’ | ‘Sequence[Axes]’ | None) – Optional. An axes to put the plot on. If not provided, the function will create a new figure, by default with constrained_layout=True, though this can be modified with figure_kw. If temperatures=”axes”, you must provide a list or tuple of two axes, the first for fluorescence, the second for temperature.
marker (str | None) – The marker format for data points, or None for no markers (default).
legend (bool | Literal[‘inset’, ‘right’]) – Whether to add a legend. True (default) decides whether to have the legend as an inset or to the right of the axes based on the number of lines. “inset” and “right” specify the positioning. Note that for “right”, you must use some method to adjust the axes positioning: constrained_layout, tight_layout, or manually reducing the axes width are all options.
stage_lines (bool | Literal[‘fluorescence’, ‘temperature’]) – Whether to include dotted vertical lines on transitions between stages. If “fluorescence” or “temperature”, include only on one of the two axes.
annotate_stage_lines (bool | float | Literal[‘fluorescence’, ‘temperature’] | Tuple[Literal[‘fluorescence’, ‘temperature’], float]) – Whether to include text annotations for stage lines. Float parameter allows setting the minimum duration of stage, as a fraction of total plotted time, to annotate, in order to avoid overlapping annotations (default threshold is 0.05).
annotate_events (bool) – Whether to include annotations for events (drawer open/close, cover open/close).
figure_kw (Mapping[str, Any] | None) – Optional. A dictionary of options passed through as keyword options to the figure creation. Only applies if ax is None.
line_kw (Mapping[str, Any] | None) – Optional. A dictionary of keywords passed to fluorescence plot commands.

Return type:

Sequence[Axes]

plot_temperatures(*, sel=slice(None, None, None), hours=None, ax=None, stage_lines=True, annotate_stage_lines=True, annotate_events=True, legend=False, figure_kw=None, line_kw=None)[source]¶

Plot sample temperature readings.

Parameters:

sel (Union[slice, Callable[[DataFrame], bool]]) – A selector for the temperature DataFrame. This is not necessarily easy to use; hours is an easier alternative.
hours (Optional[tuple[float, float]]) – Constructs a selector to show temperatures for a time range. :param:`sel` should not be set.
ax (Optional[Axes]) – Optional. An axes to put the plot on. If not provided, the function will create a new figure, by default with constrained_layout=True, though this can be modified with figure_kw.
stage_lines (bool) – Whether to include dotted vertical lines on transitions between stages.
annotate_stage_lines (bool | float) – Whether to include text annotations for stage lines. Float parameter allows setting the minimum duration of stage, as a fraction of total plotted time, to annotate, in order to avoid overlapping annotations (default threshold is 0.05).
annotate_events (bool) – Whether to include annotations for events (cover opening/closing, drawer opening/closing).
legend (bool) – Whether to add a legend.
figure_kw (Optional[Mapping[str, Any]]) – Optional. A dictionary of options passed through as keyword options to the figure creation. Only applies if ax is None.
line_kw (Optional[Mapping[str, Any]]) – Optional. A dictionary of keywords passed to plot commands.

AlreadyExistsError (either AlreadyExistsWorkingError or AlreadyExistsCompleteError) – The machine already has a folder or eds file with this run name.

Return type:

runendtime: datetime | None¶: The run end time as a datetime, taken from the log. This is the end of the run,

runstarttime: datetime | None¶

The run start time as a datetime. This is taken directly from the log, ignoring the software-set value and replacing it on save if possibe. It is defined as the moment the machine records “Run Starting” in its log, using its timestamp. This may be 3 minutes before the start of the protocol if the lamp needs to warm up. It should be the same value as defined by AB’s software.

Use activestarttime for a more accurate value.

Parameters:

path_or_stream (str or os.PathLike[str] or io.BytesIO) – A filename, open binary IO, or directory. If a directory, the file will be saved with the name from Experiment.runtitle_safe.
overwrite (bool, optional) – If True, overwrite any existing file without warning. Defaults to False.
update_files (bool, optional) – If True (default), update files before saving. Use False if you don’t want qslib to touch the files, for example, if you have just loaded a run from the machine and don’t want qslib to change anything based on its interpretation.

Return type:

spec_major_version: int = 1¶

Columns (as multi-index):

(“time”, …)float: Time of the data collection, taken from the .quant file. May differ for different filter sets. Options are “timestamp” (unix timestamp in seconds), “seconds”, and “hours” (the latter two from the active start of the run).
(well, option)float: Data for a well, with well formatted like “A05”. Options are “rt” (read temperature from .quant file), “st” (more stable temperature), and “fl” (fluorescence).
(“exposure”, “exposure”)float: Exposure time from filterdata.xml. Misleading, because it only refers to the longest exposure of multiple exposures.

qslib.processors module¶

class qslib.processors.NormRaw[source]¶

Bases: Processor

A Processor that takes no arguments, and simply passes through raw fluorescence values.

process(data)[source]¶

Return type:: DataFrame

process_scoped(data, scope)[source]¶

Filter the data, and return it (possibly not a copy), if scope is the minimum necessary scope for this normalization type. Otherwise, just return the same data.

This is useful for writing scope-agnostic code, provided that you call this for every scope before using the data.

The values for scope are: :rtype: DataFrame

“all”: the entire welldata array.
“limited”: all time points, but limited to the filter sets and samples being plotted.

ylabel(previous_label=None)[source]¶

Return type:: str

class qslib.processors.NormToMaxPerWell(stage=None, step=None, cycle=None, *, selection=None)[source]¶

Bases: Processor

A Processor that divides the fluorescence reading for each (filterset, well) pair by the max value of that pair within a particular selection of data.

The easiest way to use this is to give a particular stage (all data in that stage will be used), or a stage and set of cycles (those cycles in that stage will be used). For example:

To normalize to the mean stage 8 values, use NormToMeanPerWell(stage=8).
To normalize to the first 5 cycles of stage 2, use
NormToMeanPerWell(stage=2, cycle=slice(1, 6)).

selection allows arbitrary Pandas indexing (without the filter_set level of the MultiIndex) for unusual cases.

Bases: Processor

A Processor that subtracts the fluorescence reading for each (filterset, well) pair by the mean value of that pair within a particular selection of data.

The easiest way to use this is to give a particular stage (all data in that stage will be used), or a stage and set of cycles (those cycles in that stage will be used). For example:

stages (Iterable[Stage]) – The stages of the protocol, likely Stage.
stage (_NumOrRefIndexer[Stage]) – A more convenient way of accessing the stages of the protocol, with numbering that matches the machine.
name (str | None) – A protocol name. If not set, a timestamp will be used, unlike AB’s uuid.

Hold at a temperature for a set amount of time, with steps of a configurable fixed time.

Parameters:

temperatures – The temperature or temperatures to hold. If not strings or quantities, the value/values are interpreted as °C.
total_time – Desired total time for the stage. If this is not a multiple of step_time, it may not be the actual total time for the stage. The function will emit a warning if the difference is more than 10%. If an integer, value is interpreted as seconds.
step_time – If None (default), the stage will have one step. Otherwise, it will have steps of this time. If an integer, value is interpreted as seconds.
collect – Whether or not each step should collect fluorescence data. If None (default), collects data if filters is explicitly set.
filters – A list of filters to collect. If empty, and collect is True, then each step will collect the default filters for the Protocol.

Returns:

The resulting Stage

Return type:

Raises:

ValueError – If step time is larger than total time.

classmethod hold_for(temperature, total_time, step_time=None, collect=None, filters=())¶

Hold at a temperature for a set amount of time, with steps of a configurable fixed time.

Parameters:

temperatures – The temperature or temperatures to hold. If not strings or quantities, the value/values are interpreted as °C.
total_time – Desired total time for the stage. If this is not a multiple of step_time, it may not be the actual total time for the stage. The function will emit a warning if the difference is more than 10%. If an integer, value is interpreted as seconds.
step_time – If None (default), the stage will have one step. Otherwise, it will have steps of this time. If an integer, value is interpreted as seconds.
collect – Whether or not each step should collect fluorescence data. If None (default), collects data if filters is explicitly set.
filters – A list of filters to collect. If empty, and collect is True, then each step will collect the default filters for the Protocol.

property step: _NumOrRefIndexer[CustomStep]¶

classmethod stepped_ramp(from_temperature, to_temperature, total_time, *, n_steps=None, temperature_step=None, collect=None, filters=(), start_increment=False)[source]¶

Hold at a series of temperatures, from one to another.

Parameters:

from_temperature – Initial temperature/s (inclusive). If None, uses the final temperature of the previous stage.
to_temperature – Final temperature/s (inclusive).
total_time – Total time for the stage
n_steps – Number of steps. If None, uses 1.0 Δ°C steps, or, if doing a multi-temperature change, uses maximum step of 1.0 Δ°C. If n_steps is specified, it is the number of temperature steps to take. Normally, since there is an initial cycle of the starting temperatures, this means there will be n_steps + 1 cycles. If start_increment is True, and the initial cycle is already stepped away from the starting temperature, then there will be only n_steps cycles.
temperature_step – Step temperature change (optional). Must be None, or correctly match calculation, if n_steps is not None. If both this and n_steps are None, default is 1.0 Δ°C steps. If temperature step does not exactly fit range, it will be adjusted, with a warning if the change is more than 5%. Sign is ignored. If doing a multi-temperature change, then this is the maximum temperature step.
collect – Collect data? If None, collects data if filters is set explicitly.
filters – Filters to collect.
start_increment – If False (default), start at the from_temperature, holding there for the same hold time as every other temperature. If True, start one step away from the from_temperature. This is useful, for example, if the previous stage held at a particular temperature, and you now want to step away from that temperature. When True, note the remarks about n_steps above.

Returns:

The resulting stage.

Bases: CustomStep, XMLable

A normal protocol step, of a hold and possible collection.

Parameters:

time (int) – The step time setting, in seconds.
temperature (float | Sequence[float]) – The temperature hold setting, either as a float (all zones the same) or a sequence (of correct length) of floats setting the temperature for each zone.
collect (Optional[bool]) – Collect fluorescence data? If None (default), collect only if the Step has an explicit filters setting.
temp_increment (float) – Amount to increment all zone temperatures per cycle on and after temp_incrementcycle.
temp_incrementcycle (int (default 2)) – First cycle to start the increment changes. Note that the default in QSLib is 2, not 1 (as in AB’s software), so that leaving this alone makes sense (the first cycle will be at temperature, the next at temperature + temp_incrementcycle.
time_increment (float) –
time_incrementcycle (int) – The same settings for time per cycle.
filters (Sequence[FilterSet | str] (default empty)) – A list of filter pairs to collect, either using FilterSet or a string like “x1-m4”. If collect is True and this is empty, then the filters will be set by the Protocol.

class qslib.Experiment(name=None, protocol=None, plate_setup=None, _create_xml=True)[source]¶

Bases: object

A QuantStudio experiment / EDS file

This class can create, modify, load and save experiments in several ways, run them, and control and modify them while running.

Experiments can be loaded from a file:

>>> exp: Experiment = Experiment.from_file("experiment.eds")

They can also be loaded from a running experiment:

>>> machine = Machine("localhost", password="password")
>>> exp = Experiment.from_running(machine)

Or from the machine’s storage:

>>> exp = Experiment.from_machine(machine, "experiment")

They can also be created from scratch:

>>> exp = Experiment("an-experiment-name")
>>> exp.protocol = Protocol([Stage([Step(time=60, temperature=60)])])
>>> exp.plate_setup = PlateSetup({"sample_name": "A5"})

And they can be run on a machine:

>>> exp.run(machine)

Data can be accessed in a few ways:

The (hopefully) easiest way is with welldata, which has multi-indexes for both rows and columns.

>>> exp.welldata.loc[('x1-m4', 4), [('time', 'hours'), ('A05', 'fl')]].plot()

Or for a temperature curve:

>>> exp.welldata.loc[('x1-m4', 4), [('A05', 'st'), ('A05', 'fl')]].plot()

filterdata should still work normally.

Notes

There are a few differences in how QSLib and AB’s software handles experiments.

AB’s software considers the run as starting when the machine indicates “Run Starting”. This is stored as runstarttime in QSLib, but as it may include the lamp warmup (3 minutes) and other pre-actual-protocol time, QSLib instead prefers activestarttime, which it sets from the beginning of the first real (not PRERUN) Stage, at which point the machine starts its own active clock and starts ramping to the first temperature. QSLib uses this as the start time reference in its data, and also includes the timestamp from the machine.
The machine has a specific language for run protocols. QSLib uses this language. AB’s Design and Analysis software does not, instead using an XML format. Not everything in the machine’s language is possible to express in the XML format (eg, disabling pcr analysis, saving images); the XML format has some concepts not present in the machine format, and is generally more complicated and harder to understand. QSLib uses and trusts the machine’s protocol if at all possible, even for files written by AB D&A (it is stored in the log if the run has started).
QSLib will try to write a reasonable XML protocol for AB D&A to see, but it may by an approximation or simply wrong, if the actual protocol can’t be expressed there. It will also store the actual protocol in tcprotocol.xml, and its own representation.
By default, creating a step with a per-cycle increment in QSLib starts the change on cycle 2, not cycle 1, as is the default in the software.
Immediate pause/resume, mid-run stage addition, and other functions are not supported by AB D&A and experiments using them may confuse the software later.
QSLib writes notes to XML files, and tries to create reasonable XML files for AB D&A, but may still cause problems. At the moment, it makes clear that its files are its own (setting software versions in experiment.xml and Manifest.mf).

abort(machine=None)[source]¶

If this experiment is running, abort it, stopping it immediately.

Requires and takes exclusive Controller access on the machine.

Raises:: NotRunningError – the experiment is not currently running
Return type:: None

activeendtime: datetime | None¶: The actual end of the main part of the run, indicated by “Stage POSTRun” or an abort.

activestarttime: datetime | None¶: The actual beginning of the first stage of the run, defined as the first “Run Stage” message in the log after “Stage PRERUN”. This is not what AB’s software considers the start of a run.

property all_filters: Collection[FilterSet]¶

All filters used at some point in the experiment.

If the experiment has data, this is based on the existing data. Otherwise, it is based on the experiment protocol.

property amplification_data: DataFrame¶

property analysis_result: DataFrame¶

available_data()[source]¶

Return type:: list[str]

change_protocol(new_protocol, machine=None, force=False)[source]¶

For a running experiment and an updated protocol, check compatibility with the current run, and if possible, update the protocol in the experiment file and on the machine, changing the current run.

Changes that should be possible:

Changing the number of cycles of the current run to a higher or lower value (but higher or equal to the current cycle number), allowing stages to be lengthened, shortened, or stopped.
Adding new stages after the current stage.
Arbitrarily changing any stage that hasn’t started.

For safest results, ensure power saving is turned off in the Android software.

Parameters:

new_protocol (Protocol) – [description]
machine (Machine, optional) – [description], by default None

Return type:

change_protocol_from_now(new_stages, machine=None)[source]¶

Return type:: None

For a running experiment, change the remaining stages to be the provided :param:`new_stages` list. This is a convenience function that:

Gets the currently-running stage and cycle.
Sets the repeat number of the current stage to its current cycle, thus ending it after the end of the current cycle.
Changes the remainder of the stages to be those in the :param:`new_stages` list.

Because this does not impact any current or past stages, there is less of a need to ensure that the stages provided are compatible with the old protocol. The only check done is to ensure that, if the provided stages have any collection commands using default filters, the old protocol has specified default filters. This function does not allow the default filters to be changed: if you want to use filters other than the defaults, or defaults were not provided in the old protocol, then either specify filters explicitly (recommended) for new stages you’d like to be different, or use Experiment.change_protocol directly.

createdtime: datetime¶: The run creation time.

data_for_sample(sample)[source]¶

Convenience function to return data for a specific sample.

Finds wells using self.plate_setup.sample_wells[sample], then returns self.welldata.loc[:, wells]

Parameters:: sample (str) – sample name
Returns:: Slice of welldata. Will have multiple wells if sample is in multiple wells.
Return type:: pd.Dataframe

plot_anneal_melt(samples=None, filters=None, anneal_stages=None, melt_stages=None, between_stages=None, process=None, normalization=None, ax=None, marker=None, legend=True, figure_kw=None, line_kw=None)[source]¶

Plots anneal/melt curves.

This uses solid lines for the anneal, dashed lines for the melt, and dotted lines for anything “between” the anneal and melt (for example, a temperature hold).

Line labels are intended to provide full information when read in combination with the axes title. They will only include information that does not apply to all lines. For example, if every line is from the same filter set, but different samples, then only the sample will be shown. If every line is from the same sample, but different filter sets, then only the filter set will be shown. Wells are shown if a sample has multiple wells.

Parameters:

samples (str | Sequence[str] | None) – A reference to a single sample (a string), a list of sample names, or a Python regular expression as a string, matching sample names (full start-to-end matches only). Well names may also be included, in which case each well will be treated without regard to the sample name that may refer to it. Note this means you cannot give your samples names that correspond with well references. If not provided, all (named) samples will be included.
filters (str | FilterSet | Collection[str | FilterSet] | None) – Optional. A filterset (string or FilterSet) or list of filtersets to include in the plot. Multiple filtersets will be plotted on the same axes. Optional; if None, then all filtersets with data in the experiment will be included.
anneal_stages (int | Sequence[int] | None) – Optional. A stage or list of stages (integers, starting from 1), corresponding to the anneal, melt, and stages between the anneal and melt (if any). Any of these may be None, in which case the function will try to determine the correct values automatically.
melt_stages (int | Sequence[int] | None) – Optional. A stage or list of stages (integers, starting from 1), corresponding to the anneal, melt, and stages between the anneal and melt (if any). Any of these may be None, in which case the function will try to determine the correct values automatically.
between_stages (int | Sequence[int] | None) – Optional. A stage or list of stages (integers, starting from 1), corresponding to the anneal, melt, and stages between the anneal and melt (if any). Any of these may be None, in which case the function will try to determine the correct values automatically.
normalization (Processor | None) – Optional. A Normalizer instance to apply to the data. By default, this is NormRaw, which passes through raw fluorescence values. NormToMeanPerWell also works well.
ax (plt.Axes’ | None) – Optional. An axes to put the plot on. If not provided, the function will create a new figure, by default with constrained_layout=True, though this can be modified with figure_kw.
marker (str | None) – The marker format for data points, or None for no markers (default).
legend (bool | Literal[‘inset’, ‘right’]) – Whether to add a legend. True (default) decides whether to have the legend as an inset or to the right of the axes based on the number of lines. “inset” and “right” specify the positioning. Note that for “right”, you must use some method to adjust the axes positioning: constrained_layout, tight_layout, or manually reducing the axes width are all options.
figure_kw (Mapping[str, Any] | None) – Optional. A dictionary of options passed through as keyword options to the figure creation. Only applies if ax is None.
line_kw (Mapping[str, Any] | None) – Optional. A dictionary of keywords passed to all three plotting commands.

Return type:

plt.Axes

Returns:

plt.Axes – The axes object of the plot.

plot_over_time(samples=None, filters=None, stages=slice(None, None, None), process=None, normalization=None, ax=None, legend=True, temperatures='axes', marker=None, stage_lines=True, annotate_stage_lines=True, annotate_events=True, figure_kw=None, line_kw=None)[source]¶

Plots fluorescence over time, optionally with temperatures over time.

Line labels are intended to provide full information when read in combination with the axes title. They will only include information that does not apply to all lines. For example, if every line is from the same filter set, but different samples, then only the sample will be shown. If every line is from the same sample, but different filter sets, then only the filter set will be shown. Wells are shown if a sample has multiple wells.

Parameters:

samples (str | Sequence[str] | None) – A reference to a single sample (a string), a list of sample names, or a Python regular expression as a string, matching sample names (full start-to-end matches only). Well names may also be included, in which case each well will be treated without regard to the sample name that may refer to it. Note this means you cannot give your samples names that correspond with well references. If not provided, all (named) samples will be included.
filters (str | FilterSet | Collection[str | FilterSet] | None) – Optional. A filterset (string or FilterSet) or list of filtersets to include in the plot. Multiple filtersets will be plotted on the same axes. Optional; if None, then all filtersets with data in the experiment will be included.
stages (slice | int | Sequence[int]) – Optional. A stage, list of stages, or slice (all using integers starting from 1), to include in the plot. By default, all stages are plotted. For example, to plot stage 2, use stages=2; to plot stages 2 and 4, use stages=[2, 4], to plot stages 3 through 15, use stages=slice(3, 16) (Python ranges are exclusive on the end). Note that is a slice, you can use None instead of a number to denote the beginning/end.
normalization (Processor | None) – Optional. A Normalizer instance to apply to the data. By default, this is NormRaw, which passes through raw fluorescence values. NormToMeanPerWell also works well.
temperatures (Literal[False, ‘axes’, ‘inset’, ‘twin’]) –
Optional (default “axes”). Several alternatives for displaying temperatures. “axes” uses a separate axes (created if ax is not provided, otherwise ax must be a list of two axes).

Temperatures are from Experiment.temperature, and are thus the temperatures as recorded during the run, not the set temperatures. Note that this has a very large number of data points, something that should be dealt with at some point.
ax (Axes’ | ‘Sequence[Axes]’ | None) – Optional. An axes to put the plot on. If not provided, the function will create a new figure, by default with constrained_layout=True, though this can be modified with figure_kw. If temperatures=”axes”, you must provide a list or tuple of two axes, the first for fluorescence, the second for temperature.
marker (str | None) – The marker format for data points, or None for no markers (default).
legend (bool | Literal[‘inset’, ‘right’]) – Whether to add a legend. True (default) decides whether to have the legend as an inset or to the right of the axes based on the number of lines. “inset” and “right” specify the positioning. Note that for “right”, you must use some method to adjust the axes positioning: constrained_layout, tight_layout, or manually reducing the axes width are all options.
stage_lines (bool | Literal[‘fluorescence’, ‘temperature’]) – Whether to include dotted vertical lines on transitions between stages. If “fluorescence” or “temperature”, include only on one of the two axes.
annotate_stage_lines (bool | float | Literal[‘fluorescence’, ‘temperature’] | Tuple[Literal[‘fluorescence’, ‘temperature’], float]) – Whether to include text annotations for stage lines. Float parameter allows setting the minimum duration of stage, as a fraction of total plotted time, to annotate, in order to avoid overlapping annotations (default threshold is 0.05).
annotate_events (bool) – Whether to include annotations for events (drawer open/close, cover open/close).
figure_kw (Mapping[str, Any] | None) – Optional. A dictionary of options passed through as keyword options to the figure creation. Only applies if ax is None.
line_kw (Mapping[str, Any] | None) – Optional. A dictionary of keywords passed to fluorescence plot commands.

Return type:

Sequence[Axes]

plot_protocol(ax=None)[source]¶

A plot of the temperature and data collection points in the experiment’s protocol.

Return type:: Tuple[Axes, Tuple[List[Line2D], List[Line2D]]]

plot_temperatures(*, sel=slice(None, None, None), hours=None, ax=None, stage_lines=True, annotate_stage_lines=True, annotate_events=True, legend=False, figure_kw=None, line_kw=None)[source]¶

Plot sample temperature readings.

Parameters:

sel (Union[slice, Callable[[DataFrame], bool]]) – A selector for the temperature DataFrame. This is not necessarily easy to use; hours is an easier alternative.
hours (Optional[tuple[float, float]]) – Constructs a selector to show temperatures for a time range. :param:`sel` should not be set.
ax (Optional[Axes]) – Optional. An axes to put the plot on. If not provided, the function will create a new figure, by default with constrained_layout=True, though this can be modified with figure_kw.
stage_lines (bool) – Whether to include dotted vertical lines on transitions between stages.
annotate_stage_lines (bool | float) – Whether to include text annotations for stage lines. Float parameter allows setting the minimum duration of stage, as a fraction of total plotted time, to annotate, in order to avoid overlapping annotations (default threshold is 0.05).
annotate_events (bool) – Whether to include annotations for events (cover opening/closing, drawer opening/closing).
legend (bool) – Whether to add a legend.
figure_kw (Optional[Mapping[str, Any]]) – Optional. A dictionary of options passed through as keyword options to the figure creation. Only applies if ax is None.
line_kw (Optional[Mapping[str, Any]]) – Optional. A dictionary of keywords passed to plot commands.

Return type:: None

property root_dir¶

run(machine=None, overwrite=False, require_exclusive=False, require_drawer_check=True)[source]¶

Load the run onto a machine, and start it.

Parameters:

machine (Union[str, Machine, None]) – The machine to run on, by default None, in which case the machine associated with the run (if any) is used.
overwrite (bool or "incomplete", optional) – Whether to overwrite files if a run with the same name already exists. If “incomplete”, only overwrite if the existing run is an incomplete folder (in the experiments: working directory). By default False.
require_exclusive (bool, optional) – Whether to require exclusive access to the machine, by default False.
require_drawer_check (bool, optional) – Whether to ensure the drawer is closed before starting. Note that a close command will be sent regardless of this setting. By default True.

Raises:

MachineBusyError – The machine isn’t idle.
AlreadyExistsError (either AlreadyExistsWorkingError or AlreadyExistsCompleteError) – The machine already has a folder or eds file with this run name.

Return type:

runendtime: datetime | None¶: The run end time as a datetime, taken from the log. This is the end of the run,

runstarttime: datetime | None¶

The run start time as a datetime. This is taken directly from the log, ignoring the software-set value and replacing it on save if possibe. It is defined as the moment the machine records “Run Starting” in its log, using its timestamp. This may be 3 minutes before the start of the protocol if the lamp needs to warm up. It should be the same value as defined by AB’s software.

Use activestarttime for a more accurate value.

None if the file has not been updated since the start of the run

runstate: Literal['INIT', 'RUNNING', 'COMPLETE', 'ABORTED', 'STOPPED', 'UNKNOWN']¶: Run state, possible values INIT, RUNNING, COMPLETE, ABORTED, STOPPED(?).

property runtitle_safe: str¶: Run name with “ “ replaced by “_”; raises ValueError if name has other problematic characters.

save_file(path_or_stream='.', overwrite=False, update_files=True)[source]¶

Save an EDS file of the experiment. This should be readable by AB’s software, but makes no attempt to hide that it was written by QSLib, and contains some other information. By default, this will refuse to overwrite an existing file.

Parameters:

path_or_stream (str or os.PathLike[str] or io.BytesIO) – A filename, open binary IO, or directory. If a directory, the file will be saved with the name from Experiment.runtitle_safe.
overwrite (bool, optional) – If True, overwrite any existing file without warning. Defaults to False.
update_files (bool, optional) – If True (default), update files before saving. Use False if you don’t want qslib to touch the files, for example, if you have just loaded a run from the machine and don’t want qslib to change anything based on its interpretation.

Return type:

spec_major_version: int = 1¶

stop(machine=None)[source]¶

Columns (as multi-index):

(“time”, …)float: Time of temperature reading, for choices of “timestamp” (Unix timestamp in seconds), “seconds” (seconds since the active start of the run), or “hours”. The latter two may be negative, and may not be set if the run never became active.
(“sample”, …)float: Sample temperature for blocks 1, 2, …, 6, and average in “avg”.
(“block”, …)float: Block temperature for blocks 1, 2, …, 6, and average in “avg”.
(“other”, “cover”)float: Cover temperature
(“other”, “heatsink”)float: Heatsink temperature

property welldata: DataFrame¶

A DataFrame with fluorescence reading information.

Indices (multi-index) are (filter_set, stage, cycle, step, point), where filter_set is a string in familiar form (eg, “x1-m4”) and the rest are int.

Columns (as multi-index):

(“time”, …)float: Time of the data collection, taken from the .quant file. May differ for different filter sets. Options are “timestamp” (unix timestamp in seconds), “seconds”, and “hours” (the latter two from the active start of the run).
(well, option)float: Data for a well, with well formatted like “A05”. Options are “rt” (read temperature from .quant file), “st” (more stable temperature), and “fl” (fluorescence).
(“exposure”, “exposure”)float: Exposure time from filterdata.xml. Misleading, because it only refers to the longest exposure of multiple exposures.

writesoftware: str¶: A string describing the software and version used to write the file.

Bases: object

A connection to a QuantStudio machine. The connection can be opened and closed, and reused. A maximum access level can be set and changed, which will prevent the access level from going above that level.

By default, the class tries to handle connections and access automatically.

Parameters:

host (str) – The host name or IP to connect to.
password (Optional[str]) – The password to use. Note that this class does not obscure or protect the password at all, because it should not be relied on for security. See Security Considerations for more information.
automatic (bool) – Whether or not to automatically handle connection, disconnection, and where possible, access level. Default True.
max_access_level ("Observer", "Controller", "Administrator", or "Full") – The maximum access level to allow. This is not the initial access level, which will be Observer. The parameter can be changed later by changing the max_access_level attribute.
port (Optional[int]) – The port to connect to. If None, and ssl is None, then 7443 will be tried with SSL, and if it fails, then 7000 will be tried without SSL.
ssl (Optional[bool]) – Whether or not to use SSL. If None, then SSL will be chosen based on the port number.

A Processor that takes no arguments, and simply passes through raw fluorescence values.

process(data)[source]¶

Return type:: DataFrame

process_scoped(data, scope)[source]¶

Filter the data, and return it (possibly not a copy), if scope is the minimum necessary scope for this normalization type. Otherwise, just return the same data.

This is useful for writing scope-agnostic code, provided that you call this for every scope before using the data.

The values for scope are: :rtype: DataFrame

Bases: Processor

A Processor that divides the fluorescence reading for each (filterset, well) pair by the max value of that pair within a particular selection of data.

The easiest way to use this is to give a particular stage (all data in that stage will be used), or a stage and set of cycles (those cycles in that stage will be used). For example:

To normalize to the mean stage 8 values, use NormToMeanPerWell(stage=8).
To normalize to the first 5 cycles of stage 2, use
NormToMeanPerWell(stage=2, cycle=slice(1, 6)).

selection allows arbitrary Pandas indexing (without the filter_set level of the MultiIndex) for unusual cases.

process_scoped(data, scope)[source]¶

Filter the data, and return it (possibly not a copy), if scope is the minimum necessary scope for this normalization type. Otherwise, just return the same data.

The values for scope are: :rtype: DataFrame

“all”: the entire welldata array.
“limited”: all time points, but limited to the filter sets and samples being plotted.

scope: ClassVar[Literal['all', 'limited']] = 'limited'¶

selection: Any¶

ylabel(previous_label=None)[source]¶

To normalize to the mean stage 8 values, use NormToMeanPerWell(stage=8).
To normalize to the first 5 cycles of stage 2, use
NormToMeanPerWell(stage=2, cycle=slice(1, 6)).

selection allows arbitrary Pandas indexing (without the filter_set level of the MultiIndex) for unusual cases.

Steps may repeat their contents as well, but this is not yet implemeted.

Parameters:

stages (Iterable[Stage]) – The stages of the protocol, likely Stage.
stage (_NumOrRefIndexer[Stage]) – A more convenient way of accessing the stages of the protocol, with numbering that matches the machine.
name (str | None) – A protocol name. If not set, a timestamp will be used, unlike AB’s uuid.
volume (float) – The sample volume, in µL.
runmode (str | None) – The run mode.
covertemperature (float (default 105.0)) – The cover temperature
filters (Sequence[str]) – A list of default filters that can be used by any collection commands that don’t specify their own.

Hold at a temperature for a set amount of time, with steps of a configurable fixed time.

Parameters:

temperatures – The temperature or temperatures to hold. If not strings or quantities, the value/values are interpreted as °C.
total_time – Desired total time for the stage. If this is not a multiple of step_time, it may not be the actual total time for the stage. The function will emit a warning if the difference is more than 10%. If an integer, value is interpreted as seconds.
step_time – If None (default), the stage will have one step. Otherwise, it will have steps of this time. If an integer, value is interpreted as seconds.
collect – Whether or not each step should collect fluorescence data. If None (default), collects data if filters is explicitly set.
filters – A list of filters to collect. If empty, and collect is True, then each step will collect the default filters for the Protocol.

Returns:

ValueError – If step time is larger than total time.

classmethod hold_for(temperature, total_time, step_time=None, collect=None, filters=())¶

Hold at a temperature for a set amount of time, with steps of a configurable fixed time.

Parameters:

temperatures – The temperature or temperatures to hold. If not strings or quantities, the value/values are interpreted as °C.
total_time – Desired total time for the stage. If this is not a multiple of step_time, it may not be the actual total time for the stage. The function will emit a warning if the difference is more than 10%. If an integer, value is interpreted as seconds.
step_time – If None (default), the stage will have one step. Otherwise, it will have steps of this time. If an integer, value is interpreted as seconds.
collect – Whether or not each step should collect fluorescence data. If None (default), collects data if filters is explicitly set.

classmethod stepped_ramp(from_temperature, to_temperature, total_time, *, n_steps=None, temperature_step=None, collect=None, filters=(), start_increment=False)[source]¶

Hold at a series of temperatures, from one to another.

Parameters:

from_temperature – Initial temperature/s (inclusive). If None, uses the final temperature of the previous stage.
to_temperature – Final temperature/s (inclusive).
total_time – Total time for the stage
n_steps – Number of steps. If None, uses 1.0 Δ°C steps, or, if doing a multi-temperature change, uses maximum step of 1.0 Δ°C. If n_steps is specified, it is the number of temperature steps to take. Normally, since there is an initial cycle of the starting temperatures, this means there will be n_steps + 1 cycles. If start_increment is True, and the initial cycle is already stepped away from the starting temperature, then there will be only n_steps cycles.
temperature_step – Step temperature change (optional). Must be None, or correctly match calculation, if n_steps is not None. If both this and n_steps are None, default is 1.0 Δ°C steps. If temperature step does not exactly fit range, it will be adjusted, with a warning if the change is more than 5%. Sign is ignored. If doing a multi-temperature change, then this is the maximum temperature step.
collect – Collect data? If None, collects data if filters is set explicitly.
filters – Filters to collect.
start_increment – If False (default), start at the from_temperature, holding there for the same hold time as every other temperature. If True, start one step away from the from_temperature. This is useful, for example, if the previous stage held at a particular temperature, and you now want to step away from that temperature. When True, note the remarks about n_steps above.

Returns:

The resulting stage.

Return type:
