Hi Julian, It's pretty easy. This command will do it: setattr r type new-residue-name residue-spec e.g.: setattr r type CYX :121.a --Eric Eric Pettersen UCSF Computer Graphics Lab http://www.cgl.ucsf.edu On Jun 18, 2014, at 1:26 PM, Julian Tirado-Rives <julian.tirado-rives@yale.edu> wrote:

Dear Chimera team,

thanks for all the work you put in into a very, very, useful program. I just have a question that I am hoping is just my inability to find the proper command ... is there a way to rename a residue before writing a PDB?

I often use chimera as pre-preparation step before getting into some particular calculation packages, which often require different names for residues to indicate tautomers, protonation, etc. and it would be nice to do it from chimera rather than take the PDB's through a rather annoying set of scripts, sed's, or even text editors!

Thanks in advance,

- Julian - --
