i want to set the parameter for an input file of wannier _hamilt.in. I am
trying this for spin polarised NiO, i want to create nwan=16. I checked out
the example in quantum espresso, but there is nothing mention regarding
spin and also in on this QE forum, i am confused about how I proceed
further. the previous msg that i checked out

*&inputpp

*i am confused here  how this file i can create in spin polarsied case
from where i start for genrating nwan=16,1to 16 or 2 to 17.i am
attaching my input scf and nscf file as well.If anyone knows something
plse five your useful suggestion.*
