the helps.

There are several options.

1. Upgrade your Gromacs version; I believe -pbc mol came around version 3.3.3, so you must be using an outdated version of the software.

2. Try other trjconv options, like -center or -fit rot+trans to keep your protein centered visually.

Hi all,

what can I remove the PBC using trjconv? I used the following command:

trjconv_d -f traj.trr -s topol.tpr -pbc nojump
I've had pretty good success using:

trjconv -pbc mol -ur compact

-Justin

Thanks
