Comparison of the average number of hydrogen-bonding contacts to surface residues.

Hydrogen bonding of all valid and invalid ligands are compared across all residues that meet the surface definition. Both backbone and side-chain atoms are listed. The values and differences are given in both hydrogen bonds per residue and contacts per hydrogen-bonding atom. Due to rounding, columns may occasionally sum to a value other than 100%.
