Note that shift restraints are only available for protons in proteins and
nucleic acids (although with a little tweaking, you can make predictions for
ligands bound to proteins.) I'm not sure how big the DMSO effects would be,
but that has not been tested.

The &shf namelist is described in the manual, so I am not sure what you are
really asking with your final question.
