[Pw_forum] spin-polarized band structure calculation

Yo yo yo

I am attempting a band-structure calculation for a Cobalt chain. I want it 
to be spin-polarized. ie I want separate band structures for the minority 
and majority spins.

I attempt this by putting nspin = 2 etc etc. First I do the scf calculation 
then the nscf one as usual.

The output gives me twice amount of data as you would expect but rather 
than two sets of identical k-points with different sets of corresponding 
energies, the extra set of k-points just continues from the first set. That 
is the bands just continue further and I don't get two sets of bands.

Can anyone help / explain?
