Thanks Mark! assuming that I am interesting to obtain separate files for the each step I need just one command: mdrun -v -deffnm step7_1 -cpi step7_1.cpt -noappend that each time should create step7_1part002 etc but in case if I want to set manes of each pieces manually (it sounds crazy but in

Hi, There are some differences in recent GROMACS versions here (because the old implementations were not robust enough), but the checkpoint restart will not work with appending unless it finds the output files named in the .cpt match those on the command line (here, from -deffnm). You're making

thanks Mark! could you please also confirm that my method of the prolongation of the simulation would be correct #entend simulation for 50 ns and save these pieces as the separate files with the name step7_2* gmx convert-tpr -s step7_1.tpr -o step7_2.tpr -extend 5 mdrun -v -deffnm step7_2

In fact there is an alternative trick :-) If I rename a tpr file via gmx convert-tpr and then run mdrun using this new tpr as well as previous checkpoint, it will produce all pieces of the trajectory in the separate file: gmx convert-tpr -s step7_1.tpr -o step7_2.tpr -extend 5 mpirun -np
