I'm very sorry to made a few mistakes in my previous message. As for the process on quark gluon scattering, there is a typo when defining the scalar propagator, ScalarProduct[p] just shouldn't be squared. I can get the correct answer without using SUNTrace in the last few steps, SUNSimplify is enough at that stage. I just did a few more related QCD processes, and I think I have been much more familiar with FeynCalc now. That is fine.
