Wonderful, thank you! Guillaume On 8 Oct 2024, at 19:52, Tom Goddard <goddard@sonic.net<mailto:goddard@sonic.net>> wrote: Hi Guillaume, Seems like replacing the existing assemblies would be useful. I've enhanced the add_mmcif_assembly option of the sym command to accept the value "replace" that does that. For example sym #1 C2 add replace It will be in tonight''s ChimeraX builds dated Oct 8, 2024 or later. Thanks for the suggestion.

Using the sym command, I can store the new biological assembly in the cif file. However, it seems I can't remove the biological assembly that came with the PDB entry's annotation, but that is now completely irrelevant because I moved the coordinates into my map (when I apply it, I get new chains completely outside the map). Is there a way to do this without needing to edit the cif file with a text editor?
