[Wannier] adding two different systems or merging two systems to form one

[Zeina Al-Dolami]

Dr. Arash and Dr.Giovanni,
Thanks so much for your help. It worked and I got what I needed :)  I have
one more question that I am not sure about its answer. My question is that
what should I do to include or merge two systems together? To explain,
let's assume that I would need to find the quantum conductance for a system
that has a  carbon nano tube and a sheet of graphene. Also, let's assume
that I have already calculated the quantum conductance when they are
separated, i.e. each one is a system by itself. Now, I need to find the
quantum conductance for the whole system that has both in a device. Would
it be just identifying the positions and k points for that whole new system
or there is something else that I need to consider to investigate the
difference between bringing them together in one system and separated? Any
answer or hint is greatly appreciated. Many thanks in advance
