Hi PyMOLers,

I was wondering if it were possible to have a selection update itself for every frame.  Specifically, I have a simulation trajectory of a protein in a water box and I want to show only the waters that are within 5 Angstroms of the protein binding site.  Obviously, as the trajectory frames are moving, the waters that are within 5 Angstroms will change.  Thus, I am only interested in waters that are within 5 Angstroms to be displayed for any given frame and for waters that have moved beyond 5 Angstroms to be hidden.

Thanks!

Seam
