With this approach you will need to adjust the strip mask corresponding
to your respective states, eg. "!:1-40" and "!:1-3,5-29,31-42"

I see a screenshot apparently from pymol. How do you inform pymol
about bonds?

Leap should give you feedback when the "bond" command fails. For
visualisation you need to use a program/method that reads the
information from the topology file so that you can actually check that
it contains the wanted bonds.
