Hello Luca,

the Au case is in the process of being resolved. For graphene the input syntax depends on the version requested, for the present version something like

Solver = GreensFunction {
   ContourPoints = 30 42
    RealAxisPoints = 12
    LowestEnergy [eV] = -60.0
}

for older parser versions Eigensolver = GreensFunction {

Regards

Ben

Dear Benjamin

I did what you said. When I tried to calculate the contact for the Au
chain the code gets stuck with:

> I am sorry... cannot proceed. orbital shells should be in the order
> s,p,d

then I gave a try to the graphene_x test. In this case, the code
calculates both the contacts, however, when trying with the transport
calculation the code still complains and prints the message:

Eigensolver incompatible with transport calculation (GreensFunction or
TransportOnly required)

Best Regards
Luca
