Dear Gromacs experts, I googled for answer and I found these: http://www.gromacs.org/Documentation/How-tos/Extending_Simulations http://www.researchgate.net/post/How_to_extend_the_protein_simulation_in_Gromacs_from_1000_ps_to_10000_ps but still I am confused about what happens in my simulation. I did 5 ns simulation and I would like to add extra 5 ns on top of that so that new results (energies, temperature, trajectory, etc.) will be appended to already existing files after first 5 ns simulation. Now I used this command to run MD simulation for the first time: \$MDRUN -v -s npt-md.tpr -o mCherry7-npt-md.trr -c mCherry7-npt-md.gro -e mCherry7-npt-md.edr > $CURDIR/mCherry7-npt-md.log 2>&1 After this in the same directory I run: tpbconv -s npt-md.tpr -extend 5000 -o npt-md-ext.tpr \$MDRUN -s npt-md-ext.tpr -cpi state.cpt I tried both state.cpt and prev_state.cpt and the beginning of new simulation looks exactly the same that means temperature, energies, etc. are the same as if I started from 0ns step, not from 5ns step of previous simulation. What can cause that? Is it because of used files names or I did something else wrong?
What does the .log file say? It should clearly indicate if the restart was done by reading in the checkpoint file.
