Thanks Tsjerk,
I was confused, that why 3 files are generated as output. I will check it.
I appreciate what you said, I will read more.

Sonali,

Why wouldn't it be correct if you did just what David told you to do? And how would you be able to check yourself whether you were correct? We can't hold your hand here for every step you make. Have you already gone through the tutorial material linked on the Gromacs website? If not, please do so. In any case, try to feel more confident about yourself. You made it to academia already, didn't you?


Cheers,

Hello Sir,
Thanks for the reply,
I tried to run this commad on a simuation which I started to ran for 10 ns,and has already completed around 3 ns
I gave
trjconv -o 1ns.pdb -dt 1000 -s topol.tpr -f traj.xtc -sep


after this it asked for selecting which one I want among, System, protein,bacakbone,c-alpha etc, I selected system, and the output is three files, namely
1ns0.pdb
1ns1.pdb
1ns2.pdb
1ns3.pdb

Am I doing it correct ?


Thanks
