Dear Professor,
Currently, I am using GSAS II for Rietveld refinement analysis in Windows 8.1 OS. While I am working in ISODISTORT distortion modes, after the creation of file_child, the GM values still remain zero and I am unable to enable the "Make PDFFIT phase" button from the operations menu. I have already installed the diffpy.pdffit2 from the anaconda environment in the specific folder of GSAS II. can anyone please help me to find the solution of how to enable the option "Make PDFFIT phase" from the operation menu?
Thanks in advance
R. Rajesh
