Dear amber professors,
      I am doing the free energy calculation between the protein and Mg2+ using MM-PBSA with Amber10(both mm_pbsa.pl and MMPBSA.py),
 but many trials failed, when i check the temporary files, the following results were found in the "snapshot_lig.all.out":
MM
GB
PB
MS
1
 BOND = 0.0000 ANGLE = 0.0000 DIHED = 0.0000
 VDWAALS = 0.0000 EEL = 0.0000 EGB = -465.1086
 1-4 VDW = 0.0000 1-4 EEL = 0.0000 RESTRAINT = 0.0000
corrected reaction field energy: -733.413162
surface area = 83.647
ECAVITY = 83.647
EDISPER = 0.0000




I am confused with this, then i calculated the MM-PBSA energy of protein and the Na+, the same results was produced. Little information about this can be found by google, so i hope you can help me and give me some advices.
thank you and best wishes to you!!
