Dear Gromacs users, I am trying to extend my simulation for 200ns by using: tpbconv_mpi -s topol.tpr -extend 200000 -o topol2.tpr mdrun_mpi -s topol2.tpr -cpi state.cpt -append -maxwarn 5 >& grompp_output.log However, my simulation has only extended for 50ns. Am I doing something wrong? Thanks, Soumya
