For "-pbc nojump" to work, you need to make sure they are together (as you
want) in the first frame of your input trajectory.
The most reliable way to do this is by centering the trajectory on a
residue at the interface between the two chains (using a custom index
I've also heard some people have had luck with "-pbc cluster"
You can then run "-pbc nojump" on the centered (or clustered) trajectory.
