Hi Luciano,

It may be a good idea to think about the contents of the different
files and the meaning of the messages. If you don't provide a .trr
file, you won't have new coordinates, tpbconv will use those from the
original .tpr and effectively, you will just start the run all over!
Man..., what about tpbconv -h, and following tpbconv with -time to
select a frame for which you have positions, velocities and energies?

 Check where your trr or edr file ends using gmxcheck -f or -e. The
 shorter will be used by tpbconv for your new tpr. Specify tpbconv with
 -f and -e.

 Dear,

 Thank for your answer. I still have a problem. Do you mean (-f and -e) or (-f 
 or -e)

 I checked my trr and edr files and edr files ends first, then I typed:

 tpbconv   -s md_input.tpr -f .trr -e .edr -o md_cont.tpr

 and got the following error message:

 ++

 However, tpbconv runs without error when I provide only option -e .edr. Is 
 it correct to restart
 a calculation with the .tpr file generated with only -e .edr option. Will 
 be then possible to concatenate trajectories correctely?

 Advices,

 Thank for your time,

  Sure - as far as I know. It will generate new .tpr, which you will use for
  starting the simulation - when it is finished, simply concatenate
  trajectories, energy files with trjcat and eneconv.

As mentioned, yes you can, that's what tpbconv is for (primarily); tpbconv -h.

Sure - as far as I know. It will generate new .tpr, which you will use for

Dear Users,
 
Thank for your help. I started a 10 ns simulation, but it dies because of an error in the cluster PBS system,

so I want to continue the simulation from the last (r,v) point. May I still use 
tpbconv to restart from that last point and continue the simulation.
 
Thank again,
 


yes. take care that the time used is the same for edr and trr file.

Can you be more specific? Continue or start new simulation. Use tpbconv
to extend your simulation.
