Hello,

Thank you very much for your replies Mark and Justin.
with -deffnm option I can see all the data are written to my previous files.

one final question related to this topic:

tpbconv -s previous.tpr -extend timetoextendby -o next.tpr

Is the 'timetoextendby' the actual time or 'nsteps'? For example in the .mdp file I have the time step as 0.002 and I want to extend the simulation by 50 ns.
so should I put timetoextendby as '50000000' or '25000000'?


Neither - 50 ns is 50000 ps, not 50000000 ;)

From tpbconv -h you will see:

-extend      real   0       Extend runtime by this amount (ps)

Alternatively, one can use -nsteps, which changes the *total* number of steps (not just adding on to the end).
