Problem With Loading Monitors and Data Separately During Reduction

[PeterParker]

Within the ISIS SANS reduction we sometimes load data and monitors separately by interrogating the history of the loaded data workspace (SANSUtility.getFilePathFromWorkspace()), finding out which file the data originated from, then going back and loading the monitors from the file.

Unfortunately, our method of interrogating the history is problematic. I have seen the following error message:

Invalid value for property Filename (list of str lists)
"Y:\cycle_13_5\SANS2D00023098.raw":
File "Y:\cycle_13_5\SANS2D00023098.raw" not found

Which stems from the fact that I was using added data files given to me by Richard, which originated from a directory I no longer have access to.

Richard has also seen the following:

CloneWorkspace started
CloneWorkspace successful, Duration 0.28 seconds
RuntimeError: Failed while looking for file in workspace: __CurrentMask
at line 10928 in '`<Interface>`'
caused by line 1007 in 'C:/MantidInstall/scripts/SANS\ISISCommandInterface.py'
caused by line 455 in 'C:/MantidInstall/scripts/SANS\SANSUtility.py'
caused by line 440 in 'C:/MantidInstall/scripts/SANS\SANSUtility.py'
caused by line 431 in 'C:/MantidInstall/scripts/SANS\SANSUtility.py'

Which may or may not be the exact same problem, but speaks to the fact that loading data and monitors separately like this should be avoided if possible.
