ok, 4 files, my mistake, I checked all the files and they have RMSD among themselves of 2-3 Angstrom, can you please explain it why it is so ?

Why wouldn't they?  Are you expecting them to be the same?

You won't get much in the way of an explanation for most questions like these. Only you know the system you're studying, how flexible it might be, etc.

    0ns, 1ns, 2ns and 3ns gives four files.

        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
