Hello gromacs user,

I would like to extent a simulation by increasing the number of steps and
appending the results, unfortunately, I have already delete the .trr file
but *.xtc file and the rest are present.

So, I am invoking below commands first to extent the number of step and
then to run and append the simulation:

mpirun -x PATH -np 1 gmx_mpi convert-tpr -s prd.tpr -e prd.edr -nsteps
26000000 -o prdNW.tpr

mpirun -x PATH gmx_mpi mdrun -ntomp 1 -s prdNW.tpr -deffnm prd. -pf
pullf-prd. -px pullx-prd. -cpi prd.cpt -append

It complain about missing *.trr file while appending.

The simulation is a one windows of PMF simulation and I want to append the
I was wondering how I can extent the simulation and append the outputs with
missing the *.trr file without loosing the accuracy?
