Hi Ricardo,

I'm not sure if this is what you want, but it sounds like you are trying
to just color an approximation of the protein boundary by what is loaded
into the volumetric data. What I do is just use the quicksurf
representation for my protein (which isn't quite SASA, but is close
enough), and then color by volume. I believe the displayed points that
SASA can generate are just graphics objects, so if you are really keen
you can write a script and color them all yourself, but I think
quicksurf + color by volume is close to what you want with much less
fussing around.

Good luck!
