Computes the depth from the surface for each protein's atom.
Usage
atom.dpx(pdb)
Value
A dataframe with the computed depths.
Arguments
pdb
is either a PDB id, or the path to a pdb file.
Author

Details
This function computes the depth, defined as the distance in angstroms between the target atom and the closest atom on the protein surface. When the protein is composed of several subunits, the calculations are made for both, the atom being part of the complex, and the atom being only part of the polypeptide chain to which it belongs.
