Hi all,
I was trying to extend my simulation but I used the wrong .tpr file when I called mdrun_mpi. I didn't catch it in time and my checkpoint files were overwritten. Now I've used GROMPP to extend the simulation (as directed in http://www.gromacs.org/Documentation/How-tos/Extending_Simulations), but when I use mdrun_mpi -append with the extended .tpr file, new output files are generated anyway. Is there a way around this, or will I just have to use trjcat or something once the new run has finished?

The .cpt files contain checksums of the files that were written with them, which are checked when attempting to append later. If they don't match, mdrun is conservative and writes new files. So you will have to cut and paste later.
