You simply define a routine called user_after_single_model, and it will
be called immediately before each model is written out to disk. The
generated model is available as MODEL, so you can read in MODEL2 from
your X-ray structure and do a SUPERPOSE or ALIGN3D or whatever. See for
example http://salilab.org/modeller/manual/node91.html

Possibly a bug in Modeller - you shouldn't be seeing segmentation
faults. Send me your inputs (including PDBs) and I'll see if I can
reproduce it here.

This indicates that Modeller's guess at the number of nonbond pairs
turned out to be too small. This shouldn't occur unless you are using
atoms with unphysical Van der Waals radii, or there is a Modeller bug.
Send me a set of inputs which reproduces this problem.

This can happen at several places in the code - I can't tell what
problem you're running into without seeing your input files.
