Many thanks Nat - very useful indeed. I would however, definitely like the ability to script it. I have a series of scripts that help me deal with protein-ligand structures, and would very much like to directly incorporate this feature.

I have tried using phenix.pdbtools with either selection = "chain F or chain G or chain H" or keep "chain A or chain B or chain C or chain D" - but in both cases phenix renumbers every single residue!

If you don't mind doing it interactively, try this:

phenix.pdb_editor

(also in the GUI, of course) Still in development, but it's meant to be used for situations like this. The big drawback of course is that you can't script it.

Otherwise, what you're describing is very easy to code in Python, but it looks like pdbtools is simply not implemented this way. One of us can change that (and possibly send you a patch, if it doesn't end up being too complex).
