Description
While helping Matt it was found that running the following script
ws = mtdPEARL00071180? inst = ws.getInstrument()
origin = ws.getInstrument().getSample().getPos()
for i in range(0, ws.getNumberHistograms()):
print i, " ", ws.getDetector(i).getTwoTheta(origin, V3D(0,0,1))*180/math.pi, " ", ws.getDetector(i).isMasked()
mask = [] for i in range(0, ws.getNumberHistograms()):
angle = ws.getDetector(i).getTwoTheta(origin, V3D(0,0,1))*180/math.pi if angle > 97 or angle < 83:
mask.append(i)
MaskDetectors("PEARL00071180",WorkspaceIndexList=mask)
print "after masking" for i in range(0, ws.getNumberHistograms()):
print ws.getDetector(i).getTwoTheta(origin, V3D(0,0,1))*180/math.pi, " ", ws.getDetector(i).isMasked()
generated the following error:
RuntimeError on line 7: "Instrument: Detector with ID 6 not found. search object" in file 'mask_detectors.py' at line 7
The problem is something along the lines of histograms in the workspace exists for which no detector exists
