Hi all,

I'm currently writing a script in which I need to select all the
residues which have AT LEAST one atom within a distance of a
designated protein. Using the following commands:

set sel [atomselect top "resname X and within Y of Z"]
$sel set segname A

This only sets the segname of the atoms within Y to A, rather than all
the residues that have an atom within Y to A. This is probably
obvious.
