Hi Peter,

Same machine, all single precision.


Run gmxcheck -f -f2 on the two trajectories to see what's going on. Can you explain what you were trying to do? I see no point in the trjconv command you ran. Were there other flags that you haven't shown? Other commands that produced strange results that led you to simplify the trjconv command down to something that (in theory) doesn't do anything?

Was traj.trr output by the same machine/mdrun as the machine you are running
trjconv on?

Is traj.trr (or the mdrun that wrote it) double precision and trjconv is
compiled float (single precision)?

Hi all,

When I do the following command

trjconv -f traj.trr -o traj_1.trr

the file size of traj_1.trr is around 25% smaller than traj.trr.

Does traj_1.trr contain less data than traj.trr?

Thanks

Gil
