Dear Apu,
I know I will start up a "good" debate here, but size-strain analysis with GSAS is a non-sense. The program was not written with that purpose in mind and in fact it does not contains the instrumental aberration part of the broadening that is necessary for such computation.
Indeed it is possible to get at end some size-strain data, but quite hard as you have to do all correction later and out of the program. So it is like using GSAS for peak fitting, so better to use a peak fitting dedicated program.
Best wishes,

Dear All,
I am trying to perform Rietveld refinement on a very simple system using GSAS. I have obtained a reasonable fit except the peak widths.
I want to use the size and strain refinement option in GSAS to make the fit well.
Please tell me how to use the SIZE STRAIN refinement option in GSAS.
P.S. I am using the EXPGUI.
Thanks in advace.
Regards,
Apu
