Hi Maia, I think all you need to do is make sure phenix_env (or phenix_env.sh) is sourced after the ccp4 setup. Apparently you invoked the "phenix.pdbtools" command that comes with CCP4, and apparently the CCP4 installation isn't internally consistent. CCP4 bundles the cctbx libraries (which includes mmtbx) mainly because some parts of it are required for the compilation of phaser. I'm not surprised that the Python-based commands don't work; to my knowledge they aren't actually used in CCP4. Ralf

  Yes, this trivial combination of two commands will do it:

  phenix.pdbtools model.pdb keep=protein output.file_name=protein_only.pdb   phenix.pdbtools model.pdb keep=rna output.file_name=rna_only.pdb   phenix.pdbtools model.pdb keep=water output.file_name=water_only.pdb

Dear Pavel,

These commands did not work for me (version 1.7-650). I need to report average b factors separately for the protein, water, several ligands and ions, all of them in one chain A.
