Let $X$ be a smooth projective surface. Then, using the compactified moduli space of anti self-dual connections or torsion free sheaves we can construct Donaldson invariants of $X$. Similarly, one can take a CY3-fold and by slanting elements of the universal sheaf with elements of the Chow group of the 3fold, construct the DT (Donaldson-Thomas invariants) - at least morally I think this is the idea.

If CY3 is the canonical bundle of $X$ do the DT invariants of $K_X$ and the Donaldson invariants of $X$ relate to each other in any sense?

More generally, is there any short of relation between Donaldson and Donaldson-Thomas invariants?
