Re: FW: Query


If one decides to use models as templates for modeling, must ensure that
a good quality model has been built on the first place.  This is often
not a trivial task.

however a good quality model is usually implies a reasonably closely
related experimental structure as a template. Consequently this
experimental structure is probably a better starting point than the
model itself for future modeling studies.

So, in general I would not consider models as templates, because either
they have a highly similar experimental structure or they do not, but in
that latter case their quality is highly questionable.

best wishes,

please address your future questions to our discussion forum, many other
people could share their experience:
