Hi Again,

Still getting one warning….

Beginning GB calculations with /Users/admin/Data/TOOLS/amber14/bin/mmpbsa_py_energy
  calculating complex contribution...
  calculating receptor contribution...
  calculating ligand contribution...

Beginning PB calculations with /Users/admin/Data/TOOLS/amber14/bin/mmpbsa_py_energy
  calculating complex contribution...
Warning: inp=1 was old default
Warning: sprob=.557 not recommended for inp=1, switching to inp=1 default value: 1.400
  calculating receptor contribution...
Warning: inp=1 was old default
Warning: sprob=.557 not recommended for inp=1, switching to inp=1 default value: 1.400
  calculating ligand contribution...
Warning: inp=1 was old default
Warning: sprob=.557 not recommended for inp=1, switching to inp=1 default value: 1.400

And the final PB energy… different from tutorial

DELTA TOTAL -43.9050 2.8684 0.4056

parameters I used this time following, are there correct?

Thanks!!

Fabian
