Table of Contents
| Name | Direction | Type | Default | Description |
|---|---|---|---|---|
| InputWorkspace | Input | MatrixWorkspace | Mandatory | The name of the workspace to save |
| Filename | Input | string | Mandatory | The name to use when saving the file. Allowed extensions: [‘.ses’, ‘.sesans’] |
| ThetaZMax | Input | number | Optional | The angular acceptance in the encoding direction |
| ThetaZMaxUnit | Input | string | radians | |
| ThetaYMax | Input | number | Optional | The angular acceptance in the non-encoding direction |
| ThetaYMaxUnit | Input | string | radians | |
| EchoConstant | Input | number | Optional | The spin echo length, in nanometers, probed by a 1A neutron |
| Sample | Input | string | Sample name | |
| Orientation | Input | string | Z | Orientation of the instrument. Allowed values: [‘X’, ‘Y’, ‘Z’] |
Saves the given workspace to a file which will be formatted in the SESANS data format. A workspace with a single spectrum is expected, where the X values are wavelength and the Y values are polarisation
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]
