Re: [phenixbb] fixing backbone of selected part during phenix.refine

Hi Raja,

Does PHENIX can keep fix the backbone of a selected part in one chain during refinement using phenix.refine?

you can exclude from refinement any selected part of your structure (SA is exception).

If yes, can someone tell me the command line promt.

phenix.refine model.pdb data.mtz refine.sites.individual="not (chain A and resseq 20:50 and backbone)" More atom selection syntax examples: http://www.phenix-online.org/documentation/refinement.htm#anch82 Pavel.
