Table of Contents
| Name | Direction | Type | Default | Description |
|---|---|---|---|---|
| InputWorkspace | Input | MatrixWorkspace | Mandatory | The input workspace, which must be in units of Q |
| Filename | Input | string | Mandatory | The name of the .h5 file to save. Allowed extensions: [‘.h5’] |
| RadiationSource | Input | string | Spallation Neutron Source | The type of radiation used. Allowed values: [‘Spallation Neutron Source’, ‘Pulsed Reactor Neutron Source’, ‘Reactor Neutron Source’, ‘Synchrotron X-ray Source’, ‘Pulsed Muon Source’, ‘Rotating Anode X-ray’, ‘Fixed Tube X-ray’, ‘neutron’, ‘x-ray’, ‘muon’, ‘electron’] |
| DetectorNames | Input | string | Specify in a comma separated list, which detectors to store information about; where each name must match a name given for a detector in the [[IDF|instrument definition file (IDF)]].

| CanDirectRunNumber | Input | string | The run number for the can direct workspace. Optional. |
Saves a workspace with momentum transfer units into a file adhering to the NXcanSAS format specified by NXcanSAS Data Formats Working Group schema. If the input workspace is 2D then the vertical axis needs to be a numeric axis in momentum transfer units. The created file can be reloaded using the LoadNXcanSAS v1 algorithm.
In addition it is possible to save the transmission workspaces obtain from a reduction.
Example
import os
# Create a example workspace with units of momentum transfer
ws = CreateSampleWorkspace("Histogram",NumBanks=1,BankPixelWidth=1)
ws = ConvertUnits(ws,Target="MomentumTransfer")
LoadInstrument(ws,False,InstrumentName="SANS2D")
# Save the file
file_name = "test_file_for_nxcansas"
SaveNXcanSAS(ws,file_name)
# Load the file back
ws_loaded = LoadNXcanSAS(file_name)
#remove the file we created
alg = ws_loaded.getHistory().lastAlgorithm()
filePath = alg.getPropertyValue("Filename")
os.remove(filePath)
