Re: [PyMOL] multi-residues and -chains selection

select selection, (resi 26+57+70 in chain a) and (resi 12 in chain d) ^^^ You want 'or' not 'and'. (Think of a Venn diagram - with 'and' you are looking for residues which are in both chain a and chain d, which is impossible) Cheers, Charlie T

[PyMOL] multi-residues and -chains selection

Hello, I try to select several residues in several chains. I tried something like that : select selection, (resi 26+57+70 in chain a) and (resi 12 in chain d) but it fails. How can I Do ? thanks -- Sébastien Moretti http://igs.cnrs-mrs.fr/ CNRS - IGS 31 chemin Joseph Aiguier 13402 Marseille ce
