Jason,

one question. According to below log my GB calculations have been
successfully finished but PB (with the same input files) result in the
error during complex processing

Beginning GB calculations with
/home/own/Documents/simulations/amber/amber14/bin/sander
  calculating complex contribution...
  calculating receptor contribution...
  calculating ligand contribution...

Beginning PB calculations with
/home/own/Documents/simulations/amber/amber14/bin/sander
  calculating complex contribution...
  File "/home/own/Documents/simulations/amber/amber14/bin/MMPBSA.py", line
96, in <module>
    app.run_mmpbsa()
  File
"/home/own/Documents/simulations/amber/amber14/bin/MMPBSA_mods/main.py",
line 218, in run_mmpbsa
    self.calc_list.run(rank, self.stdout)
  File
"/home/own/Documents/simulations/amber/amber14/bin/MMPBSA_mods/calculation.py",
line 79, in run
    calc.run(rank, stdout=stdout, stderr=stderr)
  File
"/home/own/Documents/simulations/amber/amber14/bin/MMPBSA_mods/calculation.py",
line 416, in run
    self.prmtop) + '\n\t'.join(error_list) + '\n')
CalcError: /home/own/Documents/simulations/amber/amber14/bin/sander failed
with prmtop complex_dry22.prmtop!


Exiting. All files have been retained.

Why this should be and does it possible (1) look in some log file on the
reason of such error and (2) obtain results from the GB calculations only?
(this time FINAL_RESULTS file have not been created).
