Dr. Holger Gohlke ,
One more question about MM_PBSA calculations. In one of my decompose binding
energy to single residue calculations, I got the following message from log
file:\
...

Processing GB SGBTOT
Doing 1 GB SGBSOL
No values for GB_SGBSOL existing -> Skipping
Processing GB BGBTOT
Doing 1 GB BGBSOL
No values for GB_BGBSOL existing -> Skipping
....
According to AMBER manual, SGBSOL is GBSUR (hydrophobic contribution to
solvation free energy for GB calculation) plus GB (reaction field energy
calculated by GB) for side chain (S)
BGBSOL is the same value for backbone (B). I don't know exactly what is
GB_SGBSOL or GB_BGBSOL for. But they seem to be some intermediate variables
for SGBTOT or BGBTOT calculations. I don't know what these two values are
missing, while the calculation for GB TGBTOT can go through. If I get these
messages, will the calculation results be significantly effected?
Thanks very much for help.
