BAND_FORMAT = agr # This tag does not work here and I could not figure it out … WebFatbands with spin-orbit coupling A recent question touched on the case of fatband representation when spin-orbit coupling is included in the calculation ( lspinorb = .true.). I assumed that this would be straightforward and indeed there is no problem up to the last step, where plotband.x should read the band energies and projections.
