Hi,
FeynCalc5b1 gives wrong results when calculating trace of gamma5 matrix.
[in]
-——————-
tr = TR[Calc[#]] &;
tr[GA[a, b, c, d, 5]]
(* or *)
Tr[GA[a, b, c, d, 5]]

[out]
-———————–
-4 Eps[LorentzIndex[a], LorentzIndex[b],
LorentzIndex[c], LorentzIndex[d]]
-———————–
[cf. ver 4]
-———————–
-4 I Eps[LorentzIndex[a], LorentzIndex[b],
LorentzIndex[c], LorentzIndex[d]]

Thank you for your labor,
