Modeller should produce models that look like the template where the two
are aligned, by construction. Presumably you have a 1:1 alignment in
this case, since you're modeling using its own sequence - the sequence
identity is 100% ? So in this case the models should look exactly like
the template, differing only in sidechain orientations. If not,
something is very wrong - you should check the restraint violations in
the log file, because the restraints cannot be satisfied.
