SaveToSNSHistogramNexus v1

SaveToSNSHistogramNexus dialog.

Summary

Saves a workspace into SNS histogrammed NeXus format, using an original file as the starting point. This only works for instruments with Rectangular Detectors.

Properties

Name	Direction	Type	Default	Description
InputFilename	Input	string	Mandatory	The name of the original Nexus file for this data, as a full or relative path. Allowed extensions: [‘.nxs’]
InputWorkspace	Input	MatrixWorkspace	Mandatory	Name of the workspace to be saved
OutputFilename	Input	string	Mandatory	The name of the Nexus file to write, as a full or relative path. Allowed extensions: [‘.nxs’]
Compress	Input	boolean	False	Will the output NXS file data be compressed?

Description

The algorithm essentially copies the InputFilename into OutputFilename, except that it replaces the data field with whatever the specified workspace contains. The histograms do not need to be the same size (in number of bins), but the number of pixels needs to be the same.

In addition, this only works for instruments that use RectangularDetectors (SNAP, TOPAZ, POWGEN, for example); in addition, the name in the instrument definition file must match the name in the NXS file.

Usage

# Needs an SNS nexus file with rectangular detectors available from system tests
ws = Load(Filename='TOPAZ_3132_event.nxs',  LoaderName='LoadEventNexus', LoaderVersion=1)
SaveToSNSHistogramNexus(InputFilename="TOPAZ_3132_event.nxs",InputWorkspace=ws,OutputFilename=TOPAZ_3132_copy.nxs")
