Hi:
I am trying to make a selection of a sertain distance from de center of mass
of my protein and count the atoms in the selection.
I try this:

set prot [atomselect top "protein"]
 set centw [measure center $prot weight mass]
set sel1 [atomselect top "within 20 of $centw"]

and I have the following error:
syntax error
atomselect: cannot parse selection text: within 20 of 51.0234680176
50.9984474182 51.1229171753

How I cold do this??? It is possible to do?

Best regard
Anthony
