Have you cut the output up here? I can't see how the colvateBox error comes
immediately after the reading force field mod message. Are you sourcing all
of the commands from a leap script file you created? Or are you typing them
interactively into leap?

Either way we need to see all of the commands you have entered into leap so
that we can see where the error is. Also, have you created a separate DMSO
unit? Just loading the modified parameters won't help you if you don't have
a DMSO unit defined in xleap.

You will need to create a unit called DMSO with the connectivity and atom
