How can i extract the integrated intesity (calculated and observed) of individual reflections in GSAS?

I did Rietveld refinement for my x-ray diffraction data using the GSAS+EXPGUI package. The fit seems to be good. Now i wish to extract the Integrated intensity ( both calculated and observed) of...

How do i get a reliable Rietveld refinement of high pressure x-ray diffraction data containing mixed phases whose peaks are completely overlapped?

I am trying to refine High pressure(HP) xrd data of my sample using GSAS+ EXPGUI package. I have observed a structural phase transition,speculating that there are two phases originating at the...

Why the site occupancy parameter in Rietveld refinement gives a negative value?

Data was collected with a laboratory x-ray source in transmission geometry. I have tried to refine the site occupancy parameter for my sample using GSAS+EXPGUI program.The refinement was done by...
