Changeset: 005bb1978c4b1c9fad086e60206b48759f501d57

[Nick Draper]

This script should now work:

file are in autotestdata

#Load up two workspaces and mask some data
ws1=Load("GEM38370")
MaskDetectors(ws1,"100-200")

ws2=Load("GEM38370")
MaskDetectors(ws2,"300-400")

#Extract the masks to Mask Workspaces 
#this drops the data and just reatains the mask informantion
#You can still visualize these using the instrument view
#Note: ExtractMasking outputs two items you need to catch them seperately
mw1,detList1=ExtractMasking(ws1)
mw2,detList2=ExtractMasking(ws2)

#combine the masks
#Two ways to do this
#either
combinedMask = mw1+mw2
#or
MaskDetectors(Workspace=mw1,MaskedWorkspace=mw2)

#Extract the Mask to a cal file
dataDir = "C:/MantidInstall/data/"
MaskWorkspaceToCalFile(combinedMask,dataDir+"mask.cal")

#Merge this with another cal file to pick up offsets and groups
MergeCalFiles(UpdateFile = dataDir+"mask.cal", MasterFile=dataDir+"offsets_2006_cycle064.cal", \
OutputFile=dataDir+"resultCal.cal", MergeOffsets=False, MergeSelections=True,MergeGroups=False)
