[gmx-users] how to visualize gromacs trajectory

[Stephani Macalino]

Hello,
It sounds like you have to fixed broken molecules and have problem with
boundary conditions.
After doing the MD, you need to fix your trajectory first before doing
visualization.
Check this link for a workflow:
http://www.gromacs.org/Documentation/Terminology/Periodic_Boundary_Conditions


And this:
http://manual.gromacs.org/documentation/2018/onlinehelp/gmx-trjconv.html
for detailed trjconv command options.
Regards,
Steph
