Thank a lot for your response.
Now I wish to know if I use igb=2 or igb=5 keeping the default dielectric radii set then the result would be worng or not reliable at all? I am trying to calculate binding free energy from MMGBSA calculation by postprocessing a trajectory which was originally run with explicit water.
regards,
S Gupta

The term "PBradii" might better be named
"continuum_electrostatics_radii" or
"dielectric radii". They are used for both GB and PB calculations.
