Do you mean the following donor and acceptor PSF fields? Those correspond
to very old terms of the CHARMM potential that are not used any more,
because the combination of partial charges and Lennard-Jones coefficients
allows to reproduce hydrogen bonds already. Without reading corresponding
terms in the parameter file, I believe that explicit donor-acceptor pairs
will be ignored. But you should definitely verify that by checking the
energy at the first timestep.
0 !NDON: donors
0 !NACC: acceptors
