[Chimera-users] Contact in angstrom

Hello, I’m trying to measure contacts between a protein and a peptide using Chimera. I have to do this with different angstroms distances, 2, 3 and 4 Å. I'm using the command line: findclash :.A test :. B overlap -0.4 hbond 0.0 namingStyle simple save However I don’t know exactly how to modify the overlap to the desired distances. Which values can I use to measure contacts within 2, 3 and 4 Å. Thanks in advance, Arthur Pereira
