[modeller_usage] model quality: GA341, DOPE and zDOPE

[richard k belew <>]

i'm trying to evaluate models generated by Modeller in comparison
to some built using threading methods (ITasser).  GA341 seems the
primary coin-of-realm in Modeller-land, but depends on seqID
and so this can't be used (i don't think?) on threaded models.
DOPE can be, and normalized zDOPE seems recommended for
comparison of models from different homologues.

but in trying to compare models, i'm finding Modeller
models that have excellent (> 0.8) GA341 scores but
pretty terrible (1 - 1.5) zDOPE scores.  and so in comparison
to ITasser models with good zDOPE scores (~ -0.5), these
threaded models would seem preferred?

beyond the main CASP results, does anyone else have experience
trying to compare threaded vs. homologue models in terms of these
metrics, or others?  thanks for any  leads,
