Re: [Chimera-users] Saving multiple identical PDB in a single file with unique chain ID

Sorry for the confusion. By tubulin monomer I mean an alpha-beta dimer. A tubulin trimer would be three tubulins of six chains A-B-A-B-A-B, each two belonging to a tubulin monomer. My question is, if the first monomer has chains A and B, I want the copy/combine model to have different chain ID letters from A and B, for example C and D, and so on for the third, and fourth, etc. How can I do that? Regards.
