Dear DFTB+ users,

As a regular user of DFTB+, I am currently working on calculating the Green's function of a graphene nano-ribbon. In order to limit the calcultion time, I try to calculate these Green's function by a recursive method. This means that I only need to calculate the Green's function for the periodic part of the ribbon (which I get with DFTB) and then, by a Dyson's equation, I can get the whole Green's function. The problem is that I need to know the tight binding hopping terms. I think I can get these from the SKF files, but I don't know how to read them. I would be very grateful if somebody could help with this issue. I thank you in advance.

Best regards,

Mathieu
