[Wien] AFM LaMnO3

[Natalia Perkins]

Dear all,
I still have problems with afm calculations for AFM phase of LaMnO3.
I have some questions:
1.What is the main difference in the antiferromagnetic and spin-polarized
calculations? Do I understand correctly that afm simply economizes some
time by doing calculations only for spinup  and then copying them
according to the given in case.inst  "afm rules"? 
2. Should I flip spins in case.inst if now I want to try  only
spin-polarized calculations?

Thanks for a help,

Yours, Natalia Perkins
