[Pw_forum] How should I use starting_ns_eigenvalue to construct the desire occupations?

[Rui Pang]

Dear all
I am trying to calculate a system with degenerated ground states.It seems that PWSCF can control the initial orbital occupation using starting_ns_eigenvalue. However, I am confused with the output and get puzzled on how to construct the orbital occupancy. For example, the end of this mail is the information of a first scf. I guess each column is one eignevector, right? However, for colomn 5 and column 6, can not they be viewed as the same eigenvector? How should I construct a occupation with an occupied dz2 and an emputy dz2? 
If you konw, please give me some hint. I will appreciate your help.
Sincerely.
Pang Rui
