<div dir="ltr">Hi Nat,<div><br></div><div>It is the PHENIX.refine which I was using, but now I think the problem is due to the fact that there is an exact "copy" of atoms with the exact same coordinate but different atom number, which caused the failure for phenix.refine. I can delete those part to get the refinement going, but I still don't understand why the phenix.apply_ncs generate an extra copy.......</div>

</div></blockquote><div><br></div></div><div>You can run phenix.pdbtools (also in GUI, of course) on the model with no additional options, and the output will be renumbered. We can easily modify phenix.apply_ncs to do this automatically, of course, but programs really shouldn't crash on the current output.</div>
