File "/Users/anant/g2main/GSAS-II/GSASII/GSASIIpwdplot.py", line 3648, in onSave
CopyRietveld2csv(Pattern,Plot,Page,fil)
~~~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^
File "/Users/anant/g2main/GSAS-II/GSASII/GSASIIpwdplot.py", line 3612, in CopyRietveld2csv
if sum(Pattern[1][0].mask): # are there are excluded points? If so, add them too
