I am trying to calculate the trace:
Tr[GA[mu1].GA[mu2].GA[mu3].GA[mu4].GA[mu5].GA[mu6].GA[5]] under the setting $West=False, here is what I did:
$West = False
Tr[GA[mu1].GA[mu2].GA[mu3].GA[mu4].GA[mu5].GA[mu6].GA[5]]

FeynCalc returned 0, which is incorrect. I want to know what should I do to get the expected result.
