Dear Prof. Peter,
Thanks a lot for the explanation. I have another question in this regard.
Please why do we have to do spin-polarized calculation for O2 (or for
non-closed shell elements) as mentioned in the FAQ page under Calculations of
cohesive or formation energies?
Thanks very much for your time.
Kind regards.

Without SO: You can either use runafm (if you can figure out the correct
symmetry operation which transforms spin-up into spin-dn atoms) OR
runsp_lapw (takes twice as much cpu time, but is "simpler").
With SO you must use runsp. runafm does not support spin-orbit.
