Or you could use trjconv in a little script to convert the snapshots you
like to  .pbd. Use the -b and -e flags to choose the respective time

Also see
for the use trjconv non-interactively.


Good luck.

You can write this on VMD forum. Anyways you can try by doing this in
the Tcl console-

set sel [atomselect top "solvent"]
$sel get {x y z}

This would give you the coordinates of the solvent, for your purpose you
got to iterate so as to get  for each time step.

Dear All,
            I have ran a 10 ns production run for chloranil in 500
methanol solvent box. I want to get the coordinates of solvent and
solute at different time steps from the trajectory file (*.xtc). Can
anybody tell me how to extract the details using VMD or any other


You're unlikely to get help for non-GROMACS software on this mailing
list. Check out manual section 7.4 for clues on what GROMACS tools might
help, and then section 8 and appendix D for more details.
