Type

Default

Description

InputFiles

Input

str list

Comma separated list of input files

LoadLogFiles

Input

boolean

True

Load log files when loading runs

Instrument

Input

string

Mandatory

Instrument used during run. Allowed values: [‘IRIS’, ‘OSIRIS’]

SpectraRange

Input

int list

0,1

Comma separated range of spectra number to use.

SampleEnvironmentLogName

Input

string

sample

Name of the sample environment log entry

SampleEnvironmentLogValue

Input

string

last_value

Value selection of the sample environment log entry. Allowed values: [‘last_value’, ‘average’]

OutputWorkspace

Input

string

Output

Workspace group for the resulting workspaces.

Description

This algortithm is to speed up the workflow for Indirect Inelastic diffraction reduction. Uses ISISIndirectDiffractionReduction in diffspec mode with several parameters at fixed values. Also extracts the temperature from each run and creates a workspace of all runs with respect to temperature.

Usage

Example - Running IndirectDiffScan.

ISISIndirectDiffractionReduction(InputFiles='IRS21360.raw',
                                 OutputWorkspace='DiffractionReductions',
                                 Instrument='IRIS',
                                 SpectraRange=[105,112])

ws = mtd['DiffractionReductions'].getItem(0)

print('Workspace name: %s' % ws.name())
print('Number of spectra: %d' % ws.getNumberHistograms())
print('Number of bins: %s' % ws.blocksize())

Output:

Workspace name: iris21360_diffspec_red
Number of spectra: 1
Number of bins: 1934
