[Wannier] Finding Berry curvature in BZ

[Vahid Askarpour]

Dear Stepan,

I will try the Wannierberri package. The 3D visualization is particularly attractive.

Thanks,
Vahid

Is there a tool that allows the user to calculate Berry curvature in 3D and then from the visualization, deduce the coordinates of the hotspots?
