[Chimera-users] Edition of the pdb/trajectories via Chimera

[James Starlight]

Dear Chimera Users!

I have a pdb file for the 16 monomers of the coarse-grained GPCRs and
its corresponded trajectory in dcd. In both files all the monomers are
defined as the same letter of the chain (X). My question: are there an
easy way to assign a unique letter to each of the monomers in the both
files via Chimera to facilitate the further analysis ?

Thanks so much!

James
