Your cutoff for selecting atoms could be the same as the level at which you are contouring the map. You can list the selection in the Log, or write out a PDB file of the selected atoms, etc.</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>You can assign the values with the "Values at Atom Positions" tool (in menu under Tools...
