Hi John, Yes, you have several choices for density modification in phenix: 1. Use your experimental Fobs and phases as a starting point for the AutoBuild Wizard. After the first cycle, you will have density-modified phases. In this example below model-building is turned off with maps_only=True to make this go quickly: phenix.autobuild my_fobs_exptl_phases.mtz input_seq_file=seq.dat \ maps_only=True \ n_cycle_build_max=1 n_cycle_rebuild_max=0 Your density-modified phases will be in AutoBuild_run_1_/overall_best_denmod_map_coeffs.mtz after this run. 2. You can also use resolve directly in phenix with a command like this phenix.resolve<

Is there a way to do density modification in Phenix (solvent and or histogram)? If so how?

Thanks, John Bruning _______________________________________________ phenixbb mailing list [email protected] http://www.phenix-online.org/mailman/listinfo/phenixbb
