Hi,

I am using FeynCalc package in Mathematica to calculate some complicated Traces, but I think the default convention for the anticommutator of two Gamma matrices in this package is with positive a sign on the right-hand side as

${\gamma^\mu,\gamma^\nu}=+2\eta^{\mu\nu}$

I would like to change this convention to the one with a negative sign, i.e

${\gamma^\mu,\gamma^\nu}=-2\eta^{\mu\nu}$

how can I do that once for all?

Thanks,

Naser
