Hi Andreas,
I would like to introduce point mutations in a structure and quickly (and dirtily) minimize the new residue. (Best rotamer dependent on local environment, or the like.) What are simple approaches that don't involve VMD/NAMD or some such overkill.
PyMOL has a "Mutagenesis" wizard but you have to pick the best rotamer yourself.
