Methods

__init__([device_id, io, name])

adjust_gain_and_focus(parameters, *[, timeout])

Run a gain and focus adjustment from prebuilt fields and return what it found.

build_absorbance_run(wavelengths, *, ...[, ...])

RUN fields for an absorbance endpoint read (MeasurementMode 2).

build_absorbance_spectrum_run(...[, ...])

RUN fields for an absorbance spectrum (MeasurementMode 2 with no discrete wavelengths): start, stop and step in 0.1 nm, then the reference wavelengths of an endpoint read.

build_fluorescence_run(monochromators, *, ...)

RUN fields for a top fluorescence-intensity endpoint read (MeasurementMode 0).

build_fluorescence_scan_run(first, last, ...)

RUN fields for a top fluorescence scan (MeasurementMode 0, ChromaticScan1): the number of points, then the monochromator settings of the first and the last point; the reader steps evenly between them.

build_gain_focus(monochromator, *, ...[, ...])

GainPlateCommand fields for a top fluorescence gain and focus adjustment, either alone.

build_incubator(command_type, temperature)

IncubatorCommand fields: type, nominal temperature (0.1 C), channels (all).

build_luminescence_run(monochromators, *, ...)

RUN fields for a top luminescence endpoint read (MeasurementMode 1).

discover()

Parse the INIT reply (HardwareInfoResponse) into configuration and return it.

estimate_duration(read)

The run time in s the reader expects for the read read makes, without reading.

estimate_run_time(parameters)

The run time in s the reader expects for a read of the RUN fields parameters, without reading: the RUN is sent with CalcTimeOnly set, as Voyager sends it while a method is edited.

exchange(payload)

Send one logical payload and return the reply payload, under the exchange lock.

format_setup_summary()

One line describing the reader that was found.

get_temperatures()

The three incubator sensor readings in degrees C (the first is the one Voyager displays), or None when the reader reports none.

initialize()

Initialize the reader (homes the axes, about 10 s) and wait until it is ready.

measure_z_profile(parameters, *[, timeout])

Run a gain and focus adjustment from prebuilt fields with the focus, and return its focus curve.

request_status([retries])

Request the reader's status flags.

run_absorbance_spectrum(parameters, *, timeout)

Run an absorbance spectrum from prebuilt RUN fields and return one block per well, in the order the reader reads the wells; the first carries the calibration values.

run_blocks(parameters, *, timeout)

Run a read from prebuilt RUN fields and return its finished data blocks: one, or one per kinetic cycle.

run_measurement(parameters, *, timeout)

Run a read of one data block (an endpoint read or a fluorescence scan) from prebuilt RUN fields and return the block (run_blocks).

send_command(command_id[, body, retries, ...])

Send [command id] + body and return the reply payload.

setup()

Connect, initialize the reader (about 10 s), and read its configuration.

stop([accept_plate_left_in_device])

Stop a running measurement, close the drawer, and close the connection.

stop_run()

Stop a measurement running on the reader (StopCommand, StopMode 0).
Parameters:

  • device_id (str | None)

  • io (USB | None)

  • name (str)
