Hello,
I wonder if there is a quick and simple way of detecting whether a selection
exists without triggering any errors. e.g. to check if there are currently any
atoms picked (and collect the residue IDs if there is any), I do:
cmd.iterate("(lb)","stored.list.append((resi))")
if no atoms were picked, I would see the alarming error messages:
Selector-Error: Unknown keyword or selection.
Selector-Error: Malformed selection.
( ( lb<--
Is it possible to suppress them and still get the result?
Thanks in advance!
Tina
