Dear Experts,
I am still waiting for the reply, error i am facing is related to MMPBSA.py.MPI
Error: Only 'ensemble' mode supported in parallel.
thanks

Dear Experts,
I am trying to install MPI version of amber14 and ambertool14 to use MMPBSA on gpu cluster here in my university, the details are as follows:
1. The MMPBSA.py.MPI is in $AMBERHOME/bin/MMPBSA.py.MPI
2. While executing the command
$AMBERHOME/bin/MMPBSA.py.MPI -O -i mmpbsa.in -o out.dat -sp solvated.prmtop -cp complex.prmtop -rp receptor.prmtop -lp ligand.prmtop -y last2.5ns.dcd
Loading and checking parameter files for compatibility...
CHAMBER prmtops found. Forcing use of sander
sander found! Using /ghome/atyagiaa/amber14/bin/sander
cpptraj found! Using /ghome/atyagiaa/amber14/bin/cpptraj
Preparing trajectories for simulation...
/d4/atyagiaa/amber14/bin/MMPBSA_mods/make_trajs.py:631: UserWarning: Solvated topology 0 has IFBOX == 0
warn('Solvated topology %s has IFBOX == 0' % ifbox)

raise TrajError('Error running %s' % self.program)
AttributeError: 'Trajectory' object has no attribute 'program'
Exiting. All files have been retained.
application called MPI_Abort(MPI_COMM_WORLD, 1) - process 0
The error is repeatedly coming, the DO_PARRALLEL used for -np 8, before running the script.
Could you please suggest me what could be the desired solution for this problem.
One more thing I performed MD using NAMD, than converted my files using chamber. One more thing these files easily running on serial version of ambertool14.
Thanks in advance
Abhi

Hi,
this is running on gnu cluster on serial installation, I found that for the first problem when i set igb=1, MMGBSA is running, but when it is set igb=5, it shows the error
File "/ghome/atyagiaa/amber14/bin/MMPBSA.py", line 96, in <module>
app.run_mmpbsa()
File "/d4/atyagiaa/amber14/bin/MMPBSA_mods/main.py", line 218, in run_mmpbsa
self.calc_list.run(rank, self.stdout)
File "/d4/atyagiaa/amber14/bin/MMPBSA_mods/calculation.py", line 79, in run
calc.run(rank, stdout=stdout, stderr=stderr)
File "/d4/atyagiaa/amber14/bin/MMPBSA_mods/calculation.py", line 148, in run
self.prmtop))
CalcError: /ghome/atyagiaa/amber14/bin/sander failed with prmtop complex.prmtop!
Exiting. All files have been retained.
for the second problem: I have followed the installation guide as follows:
./configure -mpi gnu
make install
export DO_PARALLEL='mpirun -np 16’
make test.parallel
everything finished fine, but when I had checked AMBERHOME/bin/ their is no MMPBSA.py.MPI file in the folder.
what could be the reason
Thanks in advance
Abhi

Abhi,
What's the exact error it's giving on the GPU cluster? And have you checked
the _MMPBSA_complex_gb.mdout file to see if there's a description of
what's specifically going wrong?
For your second problem, I'm guessing it's because you haven't compiled
Amber in mpi- you can use the below in the Amber directory.
./configure -mpi gnu
make install
Best,
Kenneth

Hi,
I have following questions:
1. I am using MMGBSA for receptor-ligand interaction, the calculations
successfully finished on my PC, but when i tried on GPU cluster, I was not
able to run it, for the similar files, it shows error for complex.
2. Second problem is with mpi, i had installed on the gpu cluster
following the installation guidance provided in the Amber manual, and I
have not found MMPBSA.py.MPI on my bin directory.
Could anyone suggest me what could be the error
Thanks? in advance
Abhi
