I ran my program with FeynCalc and FeynArts package as following:

1. Create Feynman diagram with `CreateTopologies` and `InsertFields`
2. Get Feynman amplitude from `FCFAConvert[CreateFeynAmp[t2,...]`
3. Simplify amplitude with `// Contract // DiracSimplify // DiracTrick // DiracEquation`
4. Calculate loop integral with `OneLoop`

The problem occurs at this step. I get

    DiracTrick::failmsg: "Error! DiracTrick has encountered a fatal problem and must abort the computation. The problem reads: Incorrect combination of dimensions and g^5 scheme!"

How to solve this problem?

Thanks.
