Dear researcher,

I have some doubts how to considering spin-orbit coupling without spin polarization in Wien2wannier package. Thank you if you help me.

• First, when I run init_w2w -up , I don't know how I should run write_inwf correctly, ie, I want to consider 20 orbitals, 10 for up and 10 for down, but I can't use this: Atom:s,p(u,d). So, after calculation, only 10 wannier functions are calculated.

• Then, after run init_w2w, I'm not sure about running this sequence:

> x lapw1 > x lapwso

> x w2w - so -up && x w2w - so -dn

> x wannier90 -so Sincerely, Alireza
