Hi Wahab

I do have Gromacs-4.6.3 installed on my cygwin but there also I am able to
run all commands of gromacs except mdrun. sending the out put and mdlog of
mdrun for 4.6.3.
I do need Gromacs 4.5.4 as I have some comments in my paper where all work
is done on this version. Please help.
Initially with both version of Gromacs I was able to run mdrun but now I
face problem.
For mdrun_4.6.3 which is mdrun_d in my installation the error in running is
as follows
 mdrun_d -v -s prot_b4em.tpr

Back Off! I just backed up md.log to ./#md.log.2#
Reading file prot_b4em.tpr, VERSION 4.6.3 (double precision)
tMPI error: I/O or system error: No such file or directory
Aborted (core dumped)


md.log file is attached
