Dear Amber community
I try to calculate the binding energy by mm_gbsa,here's the result
ELE -8.21 7.60
VDW -20.20 2.07
INT -4.72 1.09
GAS -33.14 7.93
GBSUR -3.08 0.16
GB 10.08 5.45
GBSOL 7.00 5.40
GBELE 1.86 4.77
GBTOT -26.14 5.06
In the tutorial ,it's said the 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).
