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