The calculation is based on exposed surface area, and employs the surface area as computed by the approximate method, weighted by atom type), logarithm of the octanol/water partition coefficient (logP; it was calculated by means of atomic contributions [57, 58].
Each area is weighted by importance (approximate weights are given below).
