[ccp4bb] What is the simplest method to analytically compute the Solvent-Accessible Surface Area of a given atom in a protein?

[Francois Berenger]

Hello,

Does someone know some good articles on this particular topic?

I'd like to implement the thing myself, however if there is
a good software doing the job (with readable source code),
I might use and cite it.

Best regards,
Francois.
