why don't you just do combined TLS + individual ADP refinement, which is
the best option in most of cases?
Anyway, here is the answer to your question. If you are running
phenix.refine from the command line, the following command
phenix.refine model.pdb data.hkl params.txt
where the file "params.txt" contains these lines
strategy = *individual_sites rigid_body *individual_adp *group_adp tls \
isotropic = chain A or chain B
group_adp_refinement_mode = one_adp_group_per_residue \
group = chain C
- individual coordinates for all atoms;
- individual isotropic B-factors for all atoms in chain A and B;
- group B-factor for chain C (one B-factors per whole chain C);
- occupancies for all atoms in alternative conformations (if any present
in your structure).
Also should be able to do this using phenix.refine GUI.
Please let me know if you have any questions!
