[gmx-users] molecular surface area(MSA)?

Hi,  I was wondering whether gromacs can calculate a quantity called molecular surface area(MSA) which is different from solvent accessible surface area(SASA).
By definition, SASA of a molecule is the area of surface traced by center of a spherical water probe rolling on a vander wall surface of the given molecule. I think g_sas provides SASA.
But MSA is something different. It is the area generated by the part of the probe surface facing the given molecule. But, I am not sure whether gromacs can calculate it .
