Dear Giovanni,
Thank you for this clarification. I was using an earlier version
(wannier90-2.0.1) and my geninterp output has the following header:
# Kpt_idx K_x (2pi/ang) K_y (2pi/ang) K_z (2pi/ang) Energy (eV)
EnergyDer_x EnergyDer_y EnergyDer_z
I will switch
Dear Vahid,
Thanks for noting this.
Note that the units of k-points in the output are 1/ang and not 2pi/ang.
Accordingly, the derivatives are in units of (eV * ang), you can verify
checking with finite differences in a point with non-zero derivatives.
This will be included in the documentation
