Table of Contents
| Name | Direction | Type | Default | Description |
|---|---|---|---|---|
| Filename | Input | string | Mandatory | Name of the SESANS file to load. Allowed extensions: [‘.ses’, ‘.sesans’] |
| OutputWorkspace | Output | MatrixWorkspace | Mandatory | The name to use for the output workspace |
Loads the given file in the SESANS text format. The file begins with a number of compulsory headers, the first of which must be ‘FileFormatVersion’. There are four compulsory data columns - SpinEchoLength, Depolarisation, Depolarisation_error and Wavelength. The output workspace has X values of SpinEchoLength and Y values of depolarisation.
Example - Loading a file
import os
# Create dummy workspace
dataX = [1,2,3,4,5]
dataY = [6,1,9,14]
dataE = [1,1,4,5]
out_ws = CreateWorkspace(dataX, dataY, dataE)
out_ws.setTitle("Dummy workspace")
file_path = os.path.join(config["defaultsave.directory"], "example.ses")
# Do a 'roundtrip' of the data
SaveSESANS(InputWorkspace=out_ws, Filename=file_path, ThetaZMax=1,ThetaYMax=1, EchoConstant=1, Sample="Sample")
LoadSESANS(Filename=file_path, OutputWorkspace="in_ws")
# Retrieve loaded workspace from ADS
in_ws = mtd["in_ws"]
print("Y values of loaded workspace = " + str(in_ws.readY(0)))
Output:
Y values of loaded workspace = [ 0.796338 0. 0.179365 0.130324]
