<br>
In your structure alpha and beta are 90 deg. If you are interested in Z*(3,3) (i.e., along Z axis) then there is no need to worry about nonorthogonality of lattice vectors, similar to <a href="https://github.com/spichardo/BerryPI/wiki/Tutorial-4:-Polarization-in-GaN" rel="noreferrer" target="_blank">https://github.com/spichardo/BerryPI/wiki/Tutorial-4:-Polarization-in-GaN</a><br>
<br>
Please be cautious with the band occupancy. Can you list the results of “grep :BAN *scf”? If the structure is metallic, berrypi cannot be continued.<br>
