[gmx-users] Extending job error

[Abid Channa]

Hi gromacs users,
I am running 50 ns seconds MD  job in 5 differents parts like wise 10, 10 ns. How can I set enviroment or command through which I can run in single command. I have used gmx convert-tpr command but it requires extend command after every 10 ns time. Is there any option in gromacs that I can run 50 ns job which creates diferent trajectories after every 10, 10 ns run in single command.
Thanks in advance.
Regards,
