[Chimera-users] Selecting residues in chains defined by segname

[Francesco Pietra]

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.
