Hi All,

I am having trouble with .cif files in Chimerax — I re-built the model (Model-Angelo) in coot using alpha-fold models for completion and saved it as a .cif file. When I open the file in Chimerax certain proteins in the complex show up differently and the their chain IDs are missing in the Chimerax list. Could you help me fix this ?

Previously I was able to combine the individual alpha-fold models to a single  in Chimerax .cif file. However, if I do local refinement in coot the chains go back to being different. Please suggest. Attached is the screen shot for reference.

Thank you.
