[gmx-users] gmx trjconv

[Alex]

Dear GMX user,
I have a 110 GB trajectory from which I would like to extract only the
trajectory of the part of my interest, the rest is water. To do so, I use "
echo 1 | mpiexec_mpt -n 1 gmx_mpi trjconv -f tot.xtc -s topol.tpr -o
nonwater.skip4.xtc
-skip 4". The extracting goes very slow unfortunately. I wonder if there is
any other faster solution or suggestion to make it faster?

Regards,
Alexander
