Yes my distance restraints are long because I am using FRET distances as
distance restraints while performing MD simulations. Upon usage of this
command
mpirun -np 4 mdrun_mpi -s pr -e pr -g md -o traj.trr -c pr.gro -pd
&
I get the following error!! I did try giving yes after -pd but even then
the same error message is repeated.
Back Off! I just backed up md.log to ./#md.log.9#
