Dear Alexander,
I don't know about Topas enough to know what the format of the FCF file is. This link shows how to use FOUE to convert GSAS fourier maps into many formats, one being MapView to be used in WinGX - A Windows front end for Shelx. http://www.ccp14.ac.uk/solution/gsas/viewing_fourier_maps.html That is all I have to offer.
