i think the question should not be "how" but "why on Earth".
without any experimental data, the best any program can do
is to pull residues into the nearest favourable area, but
there is no guarantee that this will be the *correct* area
(see our 'databases' paper in acta cryst d, 1998, for an
example of this -even with x-ray data- and a discussion).
all this would amount to is (at best) cosmetic nonsense.
moreover, it could give a false impression of the quality
of the model.
