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

[Oliver Clarke]

Hi,

I’d basically like to perform the equivalent of “hide dust” on an atom selection. 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.

Cheers
Oli.
