Re: [AMBER] sander error in the decomposed MMGBSA using Ambertools12 and Amber11

Try setting use_sander=1 in your MMPBSA.py input file. The decomposition
analysis can only be run with the sander executable (e.g. it cannot be done
with mmpbsa_py_energy). By setting use_sander=0 in your input file, you may
be trying to get MMPBSA.py to use mmpbsa_py_energy for the energy
calculations instead of using sander like it should.

I am not convinced this is the issue since sander is mentioned in the
output message, but either way your input file is contradicting what the
program should be doing with a decomposition calculation anyway.
