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)"
