[Chimera-users] Open density map

[Tom Goddard]

Hi Nina,

  Chimera cannot read MTZ (structure factor) files.  You need to convert them to a map (e.g. CCP4 or MRC file).  You could do this with Phenix, search for mtz2map to find out how.

  If you are interested in atomic model refinement in a map (better than 3 Angstroms resolution) you might want to look at the ISOLDE plugin for our next generation ChimeraX  program.  You would install ChimeraX and then use menu Tools / More Tools… to install ISOLDE.
