Hi Elaine: That works fine. However, I was unable to extend your suggestions to pick up a specific residue within a specific chain. Neither "select :17 @/pdbSegment=A1" nor "select @/pdbSegment=A1 :17" are valid commands (obviously expected). On the other hand, with such complex situations, it is Xplor, with its segname features, that helps. Should you need a pdb fine with segname, I could attach a simple one, with a single chain.

Hi Francesco, Although I don’t have an example file with segnames to try myself, I’m told you can specify by the atom attribute pdbSegment, e.g.
select @/pdbSegment=A1 color red @/pdbSegment=F3
I hope this helps, Elaine ----- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco

I have a more complex case, where chains are defined by segname, for example
A1 A2 A3 A4 A5 etc
while the standard PDB definition is "A" for all them.
The same for standard "B", "C" etc.
As I want to display a movie of ligand pathways, where the ligand moves from, say, "A1" to, say, "F3", I want in the first instance become able to select particular residues in particular chains, as defined by their segname.
Could you imagine a simple way not requiring selection by atom numbers? Thanks francesco pietra
