Hello,

I am using the asymmetric unit of a PDB entry to define my own biological assembly based on a symmetric cryoEM map. 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?

Thank you,
