[Chimera-users] select atoms near at least one other atom in original selection?

[Elaine Meng]

Hi Oli,
To select all residues with any atom within 10 angstroms of current selection:

sel sel zr<10

I wasn’t totally sure if that was what you wanted. If you just want atoms and not whole residues, it would be za instead of zr.
Best,
Elaine

I have a bunch of mutation positions that I’ve mapped onto a structure, and I would like to create a subselection containing only those positions which are within lets say 10Å of at least one other postion in the original selection - basically to represent  structural clusters of mutations on the structure. Does anyone have any suggestion how to create such a selection using Chimera’s atom selection language? It seems like zr should do it but I can’t quite figure out how.
