Hi Elaine - close but not exactly. I’d like to select any residue in the current selection that is near at least one other residue which is also within the current selection - does that make sense? The idea is to identify spatial clusters within the selected residues. Maybe i’ll need to script to do this?

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.
