Comment 13 for bug 1829266

But clearly your error means that some 3/3bar information are not yet correct (or it might be something else obviously)

> LuqG := gs Ga[mu, s, r] T[a, i, j] uqbar[s, f, i].uq[r, f, j] G[mu, a];

Do. no know what this line means actually.
But I would guess that it does not include the c c~ g interaction (neither the d d~ one, ....)
I guess you need to check that ALL particle in 3/3bar state does couple to the gluon.

Cheers,

Olivier
