Re: [sdpd] Problems in refinement



dear all
when we are using the FULLPROF software for the rietveld refinement of  Li0.5Fe2.5O4, then how we will we change the coordinate of atoms (as the corresponding  space space group is 
Fd-3m).
thanks in anticipation

Others possible reasons are
- preferred orientation,
- or more classic for spinels, Fullprof uses a space group
with inversion center at the origin and the structure
description is in another setting with -1 at 1/4 1/4 1/4,
or the like, so you need to change the atomic coordinates. ..

Happy New Year,
