class mxcubecore.HardwareObjects.Gphl.GphlWorkflow.GphlWorkflow(name)[source]#

Bases: HardwareObjectYaml

Global Phasing workflow runner.

SPECIFIC_STATES#: alias of GphlWorkflowStates

adjust_dose(values)[source]#: When transmission, image_width, exposure_time or repetition_count changes, update experiment_time and use_dose in parameter popup, and reset warnings

adjust_transmission(values)[source]#: When use_dose changes, update transmission and/or exposure_time In parameter popup

calculate_recentring(okp, ref_okp, ref_xyz)[source]#: Calculate predicted traslation values using recen okp is the omega,gamma,phi tuple of the target position, ref_okp and ref_xyz are the reference omega,gamma,phi and the corresponding x,y,z translation position

collect_centring_snapshots(file_name_prefix='snapshot')[source]#

Parameters:: file_name_prefix – str
Returns:

echo_info_string(payload, correlation_id=None)[source]#: Print text info to console,. log etc.

get_available_workflows()[source]#: Get list of workflow description dictionaries.

get_emulation_crystal_data(sample_name=None)[source]#

If sample is a test data set for emulation, get crystal data

Returns:: Optional[str]

get_emulation_sample_dir(sample_name=None)[source]#

If sample is a test data set for emulation, get test data directory :param sample_name Optional[str]:

Returns:

get_emulation_samples()[source]#

Get list of lims_sample information dictionaries for mock/emulation

Returns: LIST[DICT]

handle_collection_end(dummy1, dummy2, dummy3, dummy4, dummy5, collect_dict)[source]#: Read and process collectOscillationFinished signal which means scan finished successfully

handle_collection_start(owner, blsampleid, barcode, location, collect_dict, osc_id)[source]#

Read and process collectOscillationStarted signal Used to set actual centring positions

NB only collect_dict is reliably non-null

init()[source]#: Object initialisation - executed after loading contents

static maximum_dose_rate(energy=None)[source]#

Calculate dose rate at average flux density for transmission=100

NB put here rather than in AbstractFlux as assumptions inherent in using averaging to calculate dose rates are felt to be ungeneric

Parameters:: energy (Optional[float]) – Beam enrgy in keV. Defaults to current beamline v alue
Returns:: Maximum dose rate in MGy/s
Return type:: float

parse_indexing_solution(choose_lattice)[source]#

Parameters:: GphlMessages.ChooseLattice (choose_lattice) –

Returns: tuple

post_execute()[source]#: The workflow has finished, sets the state to ‘READY’

query_collection_strategy(geometric_strategy)[source]#: Display collection strategy for user approval, and query parameters needed

query_pre_strategy_params(choose_lattice=None)[source]#

Query pre_strategy parameters.

Used for both characterisation, diffractcal, and acquisition

Parameters:: ( (choose_lattice) – obj: ChooseLattice, optional): ChooseLattice message
Returns:: Parameter value dictionary
Return type:: dict

resolution2dose_budget(resolution, decay_limit=None, maximum_dose_budget=None, relative_rad_sensitivity=1.0)[source]#

Parameters:

resolution (float) – resolution in A
decay_limit (float) – min. intensity at resolution edge at experiment end (%)
maximum_dose_budget (float) – maximum allowed dose budget
relative_rad_sensitivity (float) – relative radiation sensitivity of crystal

Returns (float): Dose budget (MGy)

Get resolution-dependent dose budget that gives intensity decay_limit% at the end of acquisition for reflections at resolution assuming an increase in B factor of 1A^2/MGy

setup_data_collection(payload, correlation_id)[source]#

Parameters:

(GphlMessages.GeometricStrategy (payload) – GeometricStrategy message
correlation_id (str) – Astra workflow correlation ID

Returns:

Return message with collection parameters

Return type:

GphlMessages.SampleCentred

shutdown()[source]#: Shut down workflow and connection. Triggered on program quit.

update_indexing_solution(values)[source]#: Update pulldowns when selected indexing solution changes

update_lattice(values)[source]#: Update pulldowns when crystal lattice changes

update_point_groups(values)[source]#: Update pulldowns when pointgroups change

update_space_group(values)[source]#: Update pulldowns when space_group changes

update_state(state=None)[source]#: Update state, resetting

class mxcubecore.HardwareObjects.Gphl.GphlWorkflow.GphlWorkflowStates(value)[source]#
