Ok.
By the way, the message that FeynCalc issues concerning TraditionalForm,
is actually not a warning, just a recommendation.
Those recommendations can be turned of with
$FCAdvice = False;
either before loading FeynCalc, or in FCConfig.m
We respect that some people prefer to use the StandardForm output
instead of TraditionalForm ;)
Cheers,
