Dear VMD,
I've run into this before and have now forgotten how to solve it
"properly".

The following snippet does not work b/c the atomcoor lists as written
are not what vecsub expects....

what's most elegant way to solve this?
thanks
Tom

************ snippet ********************
set atom1 [atomselect top { index 10 } ]
set atom2 [atomselect top { index 15 } ]

 set atom1coor [$atom1 get {x y z } ]
 set atom2coor [$atom2 get {x y z } ]
 set diff [vecsub $atom1coor $atom2coor ]
