"ELE = electrostatic energy as calculated by the MM force field.
VDW = van der Waals contribution from MM.
INT = internal energy arising from bond, angle and dihedral terms in
the MM force field. (this term always amounts to zero in the single
trajectory approach).
GAS = total gas phase energy (sum of ELE, VDW and INT).
PBSUR/GBSUR = nonpolar contribution to the solvation free energy
calculated by an empirical model.
PBCAL/GB = the electrostatic contribution to the solvation free energy
calculated by PB or GB respectively.
PBSOL/GBSOL = sum of nonpolar and polar contributions to solvation.
PBELE/GBELE = sum of the electrostatic solvation free energy and MM
electrostatic energy.
PBTOT/GBTOT = final estimated binding free energy calculated from the
terms above. (KCal/mol)"
