It is natural.
The Kohn-Sham eigenvalue does not have a spin index for noncolinear (SOI) case.
You can see it from the spinor Kohn-Sham equation.

- Dear Mitsuaki Kawamura,
Thank you so much for your reply.
How is it natural?
Do you mean that the correct result should have only 1 "BANDDAT" file?
let me explain a little more:
I have two different installed openmx (different Settings of CC, FC, and LIB) on two different servers. The same dat file gives me 2 "BANDDAT" files on one server and 1 "BANDDAT" file on another.
I want to say if it was related to "spin index", then the output files in both systems should be the same.
or I have misunderstood something here.

- Dear Maedeh,
Your original message says: "The problem exists for all SOC calculations".
When the spin-orbital coupling is included, the quantum numbers Lz and Sz are no longer conserved quantities.
Therefore it makes no sense to talk about spin up/down.

Yes, you are right. I found out what was the problem.
Thank you so much for your kind reply and help.
