Note that it is far from clear that what you want to do (effectively
pretend that you originally ran the simulation without residues 40-51)
will give correct answers anyway (assuming you fix the syntax problems.)

Energies are not pairwise decomposable, and there is no "correct" way to
just remove part of the system: what remains can no longer be assumed to
be sampling from a Boltzmann distribution.

Is it really out of the question to re-run the simulation using the
parts of the protein that you want from the beginning?
