Hi Edward, I just need to comment on this. To define contact atoms, you must use "solvated united atoms" that is atoms with implicit hydrogens where needed (united radius), this radius being further increased by that of a molecule of water. Why is that? In vacuum, it was shown that at a dist

If I remember correctly, there are two different ways to calculate a surface by rolling a ball over it, and i think that I want a program to calculate the non-conventional one. As I understand, the ASA is defined as the surface traced out by the _center_ of the rolling sphere, i.e. one radius
