[gmx-users] Dividing an MD run

[Guillem Prats Ejarque]

Actually, I'm using GROMACS 4.5.5, so, it is ok for me. I generated the new tpr file with 20 ns

tpbconv -s md_8ns.tpr -until 20000 -o md_12ns.tpr

and I ran it since the last md checkpoint:

mdrun -nt 8 -s md_12ns.tpr -cpi md_8ns.cpt -v

But, it runs 20 ns from 0, not 12 ns from 8, as it should do. What am I doing wrong?

Correct, though that page is a bit out of date, as tpbconv has been renamed
convert-tpr.
