[GSAS-II] Uncertainty of Atomic Positions Obtained from Rietveld Refinement by GSAS-II

[Toby, Brian H.]

You can find the uncertainties in the .lst file or in a .cif file if the project is exported

Dear Dr. Von Dreele and Dr. Toby,

I hope this message finds you well.

I am fairly new to GSAS-II and XRD analysis in general. I performed a Rietveld refinement on a synchrotron X-ray pattern using GSAS-II and found the atomic position of the elements present in the compound. However, the software does not report an uncertainty for the numbers and the number of significant digits after the decimal (six digits) is just too large and doesn't look practical. How one is supposed to find the uncertainty of the reported numbers by Rietveld refinement in general?

Best Regards,
Moein Adnani
