To compute the map: phenix.refine model.pdb data.mtz strategy=none main.number_of_macro_cycles=1 For more details, look "Electron density maps" section of phenix.refine documentation: http://phenix-online.org/documentation/refinement.htm Pavel. On 8/27/2008 9:53 AM, Chen Chen wrote:
Dear all, I am having a question about map calcultation. I want to calculate a 2mFo-DFc map and a mFo-DFc map to 2.0 angstrom from xxx.pdb and yyy.mtz, and zzz.cif should be supplied. Unit cell dimension and symmetry information is in the mtz file. It seems that phenix.maps can do the job, but I did not find a good document on how to run it. In its help information, a parameter file is needed. I tried do use parameter file for refinement, which has been successfully used for phenix.refine, and I ran the command phenix.maps --unused_ok yyy.mtz xxx.pdb refine.param but phenix.maps report the error

Does anyonw know what I should do to get the maps? Thanks Chen
