Are you sure that you are not looking at parts of the unit cell that
are symmetry-equivalent to the peaks found in FORSRH? You can also
use the FORPLOT program to make 2-D plots to confirm that what FOX
(or equivalently DRAWxtl) shows agrees with the internal GSAS
representation.

Hi Vincent,
I meant:
(2) that the positions of your Fourier difference peaks are not the
ones you
see by looking a the 3D Fourier difference map (exported from gsas)
in Fox ?
I guess I am using the latest version of both since I reinstalled
everything just to make I was missing something important.
Even when I put D where GSAS thinks it should be (and where I hope
it should be as well), then it turns out that this site or those
sites are hardly occupied (and they are those to be supposingly
where the scattering is from).
Cheers
