SaveParameterFile dialog.
Table of Contents
| Name | Direction | Type | Default | Description |
|---|---|---|---|---|
| Workspace | Input | MatrixWorkspace | Mandatory | Workspace to save the instrument parameters from. |
| Filename | Input | string | Mandatory | The name of the file into which the instrument parameters will be saved. Allowed extensions: [‘.xml’] |
| LocationParameters | Input | boolean | False | Save the location parameters used to calibrate the instrument. |
This algorithm allows instrument parameters to be saved into an instrument parameter file. The parameter file can then be inspected and or modified. It can also be loaded back into Mantid using the LoadParameterFile v1 algorithm.
The LocationParameters property specifies whether or not to save any calibration parameters used to adjust the location of any components. If enabled, SaveParameterFile may also output “x”, “y”, “z”, “rotx”, “roty”, and “rotz” parameters when necessary to update the position and rotation of the components.
import os
#Create a path in the user's home directory
filename = os.path.expanduser("~/params.xml")
#Load a workspace
ws = Load(Filename = "MAR11001.raw")
#Save the workspace's instrument's parameters to the given file.
SaveParameterFile(Workspace = ws, Filename = filename, LocationParameters = False)
#Make sure the file was written successfully
if os.path.isfile(filename):
print "Parameters written successfully."
Parameters written successfully.
