LoadNXcanSAS dialog.
Table of Contents
| Name | Direction | Type | Default | Description |
|---|---|---|---|---|
| Filename | Input | string | Mandatory | The name of the NXcanSAS file to read, as a full or relative path. Allowed extensions: [‘.nxs’, ‘.h5’] |
| OutputWorkspace | Output | Workspace | Mandatory | The name of the workspace to be created as the output of the algorithm. A workspace of this name will be created and stored in the Analysis Data Service. For multiperiod files, one workspace may be generated for each period. Currently only one workspace can be saved at a time so multiperiod Mantid files are not generated. |
| LoadTransmission | Input | boolean | False | Load the transmission related data from the file if it is present (optional, default False). |
Loads the given file, which should be in the NXcanSAS format specified by NXcanSAS Data Formats Working Group schema http://cansas-org.github.io/NXcanSAS/classes/contributed_definitions/NXcanSAS.html and creates an output workspace. The current loader is optimized to work with NXcanSAS data which was saved using the SaveNXcanSAS v1 algorithm.
If the file contains transmission workspaces then they can be loaded into separate workspaces.
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)
