Dear Developer,
Thanks for the instructive codes and I find it very helpful. I wonder if it is possible to convert the model Hamiltonian into the wannier90.dat format, which is quite widely used in calculations by wannierberri (https://github.com/wannier-berri/wannier-berri) and wanniertools (https://github.com/quanshengwu/wannier_tools)?

Regards,
Dongsheng
