[chimerax-users] Chnage Chain IDs

Greetings to all, In UCSF Chimera tools, there's an option to change chains ID/names. Unfortunately, I can't save my model under a cif format. While in Chimera X , I can save a model under a cif format but can't change the name of my chains, or at least I'm not able to find the command for that. My main goal is to have my model under a cif format with my new naming system, any idea on how I can solve this problem? Ramy Kazan PhD Student
