You have to look at the bands lying only underneath the light cone only. MPB won't do this for you -- the "Gap" information it prints out is only for overlapping gaps at *all* the k points, which is not correct for an index-guided structure like this. You can compute the gap in MPB, of course, but you have to have it compute the bands and then compute the gap yourself.
