I am running FeynCalc 4.1.1 on Mathematica 7.01 (Unix machine).

The command DiracTrick[] doesn’t work at all. If I try to evaluate trace, the DiracTrick comes back in the output. I’ve tried the examples in the Help, and non of them work.

I’ve figured out how to solve this: using Calc. For example:

Tr[ … //Calc]

does the job. But sometimes it is really inconvenient putting Calc everywhere. Do you have any idea what problem am I facing?

Thank you in advance,

Luka
