Hi Warren,
Thanks! That did the trick.
All the best,

This is something PyMOL didn't handle well until recently, but I
think you
can now prefix the minus sign with a backslash in order to force
PyMOL to
interpret the value numerically instead of as a range.
# create some negative residue identifiers
load $TUT/1hpv.pdb
alter chain A, resi=int(resi)-200
set seq_view
# test selections
indicate resi \-127
indicate resi \-136-\-129
A bit ugly, but it works!
Cheers,
Warren

Subject: [PyMOL] Selecting Negative Residues
Dear All,
Does anyone know how to select residues with negative sequence
numbers in
Pymol?
I have a protein molecule with two residues with negative sequence
numbers
(-2 and -1). When I issue the command:
cmd.select('temp', 'resi -2 and name CA')
Pymol selects the alpha carbons of residues -2 to +2.
How can I tell Pymol that I don't want to select a range?
Thanks, and all the best,
--Buz
