Respected Sir,
Now I am trying an REMD simulation on a peptide in
cluster. The command line I used as follows
mpirun -np 6 /usr/local/gromacs/bin/mdrun_mpi -s sd_.tpr -multi 2
-replex 1000 -reseed 175320
But this command line getting error like this
Wrote pdb files with previous and current coordinates
