Hi Francesco, You can do that with commands. For example, here is the command to select residues in model #0 within 4 angstroms of residues 20,30-40,55 of model #1: sel #0 & #1:20,30-40,55 z<4 or you could use "za" instead of "z" for an atom-based instead of reside-based cutoff. <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/atom_spec.html#zones

What I would like to do is a global search of which residues of model #0 are within a certain distance from which residues of model #1. Where "model" stands for a protein in both cases. That would save time in simulations of docking (not using DOCK) between proteins. I can locate with Chimera key residues, but their number is large. Thanks francesco pietra
