[Pw_forum] spin orbit and custom occupations

Thanks Andrea,

but this doesn't really solve my problem...

I still can't find from example06 how to check the final occupations.
If I use nspin=4, which is supposed to be spin-polarized, unlike in the
case of nspin=2, I only get a single row of occupations, like this

     occupation numbers
     1.0000   1.0000   1.0000   1.0000   1.0000   1.0000   1.0000   1.0000
     1.0000   1.0000   1.0000   1.0000   1.0000   1.0001   0.9219   0.1150
    -0.0167  -0.0202   0.0000   0.0000   0.0000   0.0000   0.0000   0.0000

But which of them are up or down? or, how can I find out whether I have a
singlet or a triplet in my single isolated atom?

  Thanks in advance
