Not at present.

It uses a brute-force approach based on VDW
spheres of surface atoms and hypothetical waters-in-contact. It is spread over
multiple source files, but RepSurface.c has the top-level code.

Dear all,

Once again, I need some help from pymol experts. I would like to select
surface residues via the surface calculation algorithm of Pymol. Is this
possible? What is the surface calculation algorithm that Pymol use and is
it scattered among many source-code files or is it contained in just one
source-code file?

Thanks in advance.

Best,

Quyen
