hello!
When i called GA[], i found it that the gamma matrix with a bar, and the
function GS[] is also the same. So why? how to solve it?
Oh, i forgot it. My FeynCalc's version is 9.2.0, and i heard it that the old version was normal, not with a bar, is't the problem of version?
My email is 540714059@qq.com
Thank you!
