I might be missing something, but the fobs-(fobs-fcalc) map to me seems
like a simple fcalc map, where it's not too surprising that you see
something...
Which PDB model did you use as a phase_source in
phenix.fobs_minus_fobs_map?
If you like, you can send me the two data files and a PDB file and tell
where you are expecting to see the differences. I will then play with
this...
Pavel.
