FeynCalc manual (development version)

FCGVToSymbol

FCGVToSymbol[exp] converts objects of type FCGV["sth"] in exp to symbols using ToExpression["sth"].

The option StringReplace can be used to specify string replacement rules that will take care of special characters (e.g. ^ or _) that cannot appear in valid Mathematica expressions. SMPToSymbol is useful when exporting FeynCalc expressions to other tools, e.g. FORM.
