I have a 500 ns molecular dynamics trajectory with several proteins in a membrane. The entire system is enclosed in a periodic box. Unfortunately, my proteins are only interacting around the interfaces of the periodic box's edges. I would like to visualize these interactions in a more natural fashion. Is there a way to adjust the "camera perspective" on my trajectory in VMD? That is, I want to move the view of the edges of the box so that I can see what is happening with my proteins.
