[gmx-users] trjconv for cutting the trajectory in small subtrajectories

[Mahboobeh Eslami]

 hi GMx user I simulated protein-ligand comolex with gromacs. total simulation time is 20ns. when I use trjconv for cutting the  trajectory  in  small   subtrajectories from 10000ps to 17000ps by following command:
trjconv -f md.xtc -s md.tpr -n index.ndx -e 10000 -b 17000  
I see following text in terminal window;
Reading frame       0 time 10000.000   
Precision of md-nopbc.xtc is 0.001 (nm)
Using output precision of 0.001 (nm)
 ->  frame   3500 time 17000.000        ->  frame   3000 time 16000.000
I think the generated trajectory is incomplete because saved frame is incomplete. please guide me.
Many thanks tobest
