Hi George,
You do NOT need to generate a volume or use sop clip.  It’s just a clipped molecular surface.

You can just follow all the steps in the B-factor coloring image tutorial.  If you don’t want to do the coloring part you could skip just that part.  The feature highlight you mention has an “image how-to” link that goes to that tutorial.

Best,

If this is the routine, I’m seeking advice on how to generate the volume data and then pass it to the sop clip command.
