Professor, I met a problem when using FC5:

DiracTrace[GA[m].(GA[n].GA[6] + GA[n].GA[7])]

gives result 0,while

Calc[DiracTrace[GA[m].GA[n]]]

gives non-zero result.

As GA[6]=(1+GA[5])/2 and GA[7]=(1-GA[5])/2, I guess it is a bug. The method "tr = TR[Calc[#]]&; " also seems not useful for the problem.

Could you tell what the metter is?

Thank you very much!
