    So the Decision Tree operators don't natively output the gain ratios on each branch. I believe, however, that the information is definately created but not outputed. I wonder if some Groovy Script can help here. @mschmitz any ideas?

    No. But we do have a unicorn mask and sometimes he is pretty jumpy.
