[Pw_forum] band structure in noncollinear calculation

The concept of "majority/minority" spin is ill defined in a non-collinear structure, because different spin components do not commute with each other. SB

In the band structure result which is attached, the bands start to split in the s->gamma path. I am not quite understand this result because I expect to see the degenerate majority/minority bands. Moreover, how can I separate majority/minority bands in the noncollinear case? Thank you in advance for any help you can provide.
