Dear Gromacs users,
I use Gromacs 4.5.1. The problem relates to the restarting procedure of a run. Usually I restart the run with
the "-append" option and now I need to move the ".trr" and ".xtc" files to
another directory since they got too big for the directory quota where they were located by now. So,
previously the restart line looked like the following:
mdrun -append -s system.tpr -c system.gro -g system.log -e system.edr -cpi
system.cpt -cpo system.cpt -o system.trr -x system.xtc
and now after copying (or just moving) the ".trr" and ".xtc" files to a new
directory the restart line looks like:
dir=new_dir
mdrun -append -s system.tpr -c system.gro -g system.log -e
system.edr -cpi system.cpt -cpo system.cpt -o ${dir}/system.trr -x
${dir}/system.xtc
However, in the latter case Gromacs gives the error "output files not present or named differently:..." complaining that the
".trr" and ".xtc" files could not be found in the location pointed by the checkpoint ".cpt" file. This is
even when the copy of the original ".trr" and ".xtc" files were left in their original directory.
Could anybody point to a solution or a workaround ?
Use -noappend and concatenate later.
