[QE-users] How to separate the spin-up and spin-down electronic band structure?

[Zhibin GAO]

Dear all,

I want to calculate the band structure with the SOC effect. However, after
setting three variables:
noncolin=.true.
lspinorb=.true.
starting_magnetization(1)=1.0   ! 1.0 is just an example and a non-zero
number is to break the time-reversal symmetry.

But I always get:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     task #         1
     from punch_bands : error #         1
     incorrect spin_component
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Could someone give me a suggestion? Thanks for your kind help!

Best wishes,
