Hi dears, I'm performing PWcond calculations on a cubic unit cell. I obtain 5 output files, like bands.AB.re, bands.AB.im, bands.AB.co_re, bands.AB.co_im and bands.AB.3d. I want to plot the complex band structure for the material AB and therefore my questions are as follows:

1/ what represent files .co_re, .co_im and .3d?

2/ which files that are supposed to be plotted?

3/ what are the allowed values of K_perp and why the weight is 1 or 0, and what does represent nenergy (the number of energy)?

Thank you for your assistance,

Ahmed
