Hi

I guess you need to re-imaging back the primary box.
This is well explained in Tutorial B1 Section 5, at the end when they explain how to visualize a trajectory.
(You need to write a simple script and run it in cpptraj).

In addition, which option do you use in vmd when you load the mdcrd file?
You have to option and I think you shoul use as format " Amber coordinates with Periodic Box". Did you already use this format?

Hope this help.

Valentina

To my previous question: I attached a picture from vmd where I simply
loaded the prmtop and mdcrd file and this is what I got... the water is
very strange. What could be the problem?

Thank you in advance for your help.
