[gmx-users] Viewing large trajectory files

[Tsjerk Wassenaar]

Hi Viswanadham,

If you only want to know the time of the last frame you can issue:

grep t= trajectory.gro | tail -1

which will give you the title line for the last frame (including the
time). If you want to extract the last frame, you can do it with
trjconv, using the .gro trajectory file for both options -f and -s
(though -s should be optional :S)

Hope it helps,

Tsjerk
