To my knowledge in GSAS it's not possible to perform the structural refinement of the same phase with two kinds of profile model functions, one for sharp peaks and the other for broadened peaks (I already saw that the function n.4 by Stephens doesn't match my case). It is possible with Fullprof. I

Dear Crystallographers, I have a problem with the refinement of a structure in which both sharp and broadened peaks appear in the neutron powder diffraction profile. The broadening of low intensity peaks is probably due to the existence of a supestructure. To my knowledge in GSAS it's not possible
