[PyMOL] Surface and SASA

[Kaushik Raha]

Maybe this has already been discussed but I was wondering if the 
surface that PyMOL generates is solvent accessible surface area (SASA) 
? If so what is the solvent probe radius? The reason I ask is some 
atoms seem to have exposed surfaces when rendered with PyMOL whereas my 
SASA program has it as non-exposed.

Another question I have is does PyMOL read AMBER topology (prmtop) 
files? And how do I load it and read it along with a crd file?

Thanks in advance.
