Hi, Bernhard,
To clarify my previous e-mail, in both cases the maps are being
calculated from weighted coefficients from an MTZ file output by the program.
I tried calculating a weighted 2Fo-Fc map in CCP4i using the PHENIX
MTZ file and the end-result (red bars) was the same.

Hi Pedro,
this is due to the map sampling (which seems different between the
two programs). Anyway, for now you can change the weighting manually:
Extensions->Refinement->Set Density Fit Graph Weight

Hi,
I encountered a strange problem while running the "Density Fit Analysis"
widget on a structure refined with PHENIX. All residues are represented
with a red bar (see picture) with low CC.
Using the same input coordinate and MTZ file in REFMAC produces normal
"Density Fit Analysis" graphs (see picture).
I am at a loss to understand why this is happening...
This happens with both 0.6.2 and 0.7 versions of Coot.
Best regards,
Pedro.
