Dear Chimera Users,

 

I have a cryo-em map file and I would like to convert it into a PDB file. How can I do that? I tried saving the .pdb file but it throws an error saying “No model chosen to save”.

Another question, If I open a .map file of a protein complex in Chimera, how can I select a subregion (a particular chain) and colour the surface of that part differently? I am not able to select the chain when I upload the .map file.

Thank you,

Aditya
