Dear Jérôme,
I think that the mutator does a great job. It's important though that the
user is aware of that. Running psfgen and alchemify manually solves the
problem for me. There, I generally leave the backbone atoms and the Cbeta
of the target side chain in place and let "guesscord" (resp. IC PARA - IC
BUILD in CHARMM) reconstruct the rest.
Regards,
Gianluca
