Nandini, GSAS gives R(F^2) which is sometimes defined for single crystal structure analysis. It can be used in the same way as RBragg. Neither is statistically related to the minimization process in a Rietveld least squares refinement, but can be a useful diagnostic for the quality of the structural fit to the reflection intensities.

Does GSAS suit give this parameter? __________________________________ Do you Yahoo!? Get better spam protection with Yahoo! Mail. http://antispam.yahoo.com/tools
