Ensemble refinement with covalent ligands - bond length > 5Å
Dear all, I am running phenix.ensemble_refinement on a covalent protein-ligand complex providing the same parameter-files used for phenix.refine. I also included the .def and .cif files generated by phenix.ligand_linking. However, in quite a few of the ensemble structures, the covalent link exceeds 5Å, which is obviously wrong. How can I obtain ensemble structures with reasonable covalent bond length? Best, Eike ———————————————————————————— Dr. Eike C.

Elke Can you send the files so I can check? Also what version are you using? And are you using the GUI? Cheers Nigel --- Nigel W.
