[Pw_forum] Unable to separate respective spin eigenvalues?

[Henry J Seeley]

Hello QuantumEspresso community,

I finished performing some spin-orbit calculations on Lead Sulfide, and 
I'm now attempting to separate out the electron bands with respect to 
their spins (up/down). Using 'bands.x' with the 'spin_component' option, 
I hoped to receive spin up or down eigenvalues. I'm having some trouble 
however; when I try this option on 'spin_component=1', I receive all my 
bands back (no spin separation), and when I use 'spin_component=2' I get 
the following error:

"
      Error in routine punch_bands (1):
      incorrect spin_component
"

Perhaps this is related to my XC functional or pseudopotential?
Here are the relevant parts of my SCF input file:


"
&CONTROL
   ...
   wf_collect = .true. ,
   verbosity = 'high' ,
/

&SYSTEM
...
   noncolin = .true. ,
   lspinorb = .true. ,
