Dear CCP4BB, Has anyone encountered the following problem when using Coot (coot-0.6.2pre) validate density fit analysis with an mtz file calculated using phenix.refine (1.6.4)?
All of the density fit values are exactly 0.0 (all bars same height and red) when using a 2Fo-Fc map calculated from an mtz file output by PHENIX Version: 1.6.4, Release tag: 486, Platform: intel-linux-2.6 redhat-e5.5. Density fit analysis worked fine when I was using mtz files from PHENIX Version: 1.6.2, Release tag: 432, Platform: intel-linux-2.6 redhat-e5.5. Thus, it appears to be an issue with the new version of phenix. I should mention that the maps from 1.6.4 mtz files display fine in Coot and real space refinement against those maps in Coot works fine too. It is just the density fit analysis utility that seems to be problematic. Thanks, Jack Tanner -- John J.
