HI,
Try this command before you run you mm_pbsa.py
"source <path_to_amber_home>/amber.sh" for bash with quotes
or
"source <path_to_amber_home>/amber.csh" for csh with quotes

Subject: [AMBER] error running mmpbsa
Dear all,
I am doing some MMPBSA calculations using the dollowing input and command
line:
--- mmpbsa.inp
&general
endframe=2201, keep_files=2, interval=6,
/
&gb
igb=2, saltcon=0.100,
/
&pb
istrng=0.100,
/
--- command line
MMPBSA.py -O -i mmpbsa.in -o FINAL_RESULTS_MMPBSA.dat -cp
./0_make_tutto/tutto.top -rp ./0_make_azzurro/azzurro.top -lp
./0_make_rosa/rosa.top -y tutto.mdcrd
However, the calculation crashes and I am having the following error:
Loading and checking parameter files for compatibility...
mmpbsa_py_energy found! Using
/net/software/pkg/amber/amber14-test/bin/mmpbsa_py_energy

TrajError: /net/software/pkg/amber/amber14-test/bin/cpptraj failed when

Exiting. All files have been retained.
I have successfully preformed MMPBSA calculations in the past and I can not
understand what is gouing wrong.
It seems that it can not read the trajectory of the complex. But I have
checked it and it seems OK.
Do you have any idea?
thank you
Giulia
