Hi Sara, > # Extract the first part of the trajectory > trjconv -s md.tpr -f md.trr -n index.ndx -o 1a.xtc -e 19999
That should be -e 199999 :) But you can also use -e 200000. Probably that is better. I first thought it'd be better to avoid a double frame, but since trjcat is used to combine the parts again, it doesn't matter. Good luck, Tsjerk -- Tsjerk A.
