Dear Vladyslav,
I have a problem with the use of the Schouten identity:

1) it exist, but it does not appear in the online manual
http://feyncalc.org/FeynCalcBook/

2) acting on a given expression A with Schouten[Calc[A]] is fine
(my expression is 0 after using Schouten, as it should),
but if I do SetOptions[Contract, Schouten -> True]
or SetOptions[Calc, Schouten -> True] (in practice Calc,
so SetOptions[Contract, Schouten -> True] should be enough),
my expression does not vanish without using Calc.
Why?

Thanks in advance for your help.

Best

Samuel Wallon
