Hi Anindito. We couldn't say what the "sym" command would be without knowing what information is in the structure file (PDB or mmCIF). If there is not symmetry information in the file then you have to specify it in the command instead, which can be difficult. However, maybe what you really want is "fitmap" with symmetrical fitting (instead of making copies with "sym" first). In that case your density map must have symmetry information. See "fitmap" help and video: <https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/fitmap.html#symmetri...> <https://www.cgl.ucsf.edu/chimera/videodoc/SymFitDNAb/> I hope this helps, Elaine ----- Elaine C.

Dear All,
What will be the correct complete command (sym) for making copies of an atomic structure and symmetrize them to dock in the relevant density map.
Stay safe & Regards
