spin orbit NSCF calculation

[giacomo giorgi]

Good morning,
I am doing SOC calculations on some perovskites structure. I optimized the structure and got a reasonable geometry. On top of it I want to do a bandstructure calculation. From the INCAR below I get a PROCAR file empty. Can anyone kindly tell me where I am wrong? (Actually, I am very new with SOC and for this reason I tried to use the default for most of the SOC parameters). Thanks!

INCAR:
--------
SYSTEM = SrTaO2N

# xc
GGA = PE
ISTART = 1

#electronic relaxation
LREAL = Auto
PREC= High


ISMEAR = 0
SIGMA = 0.05
NELMIN = 4
NELM = 200

ISPIN=2

IBRION = 1

#accuracy of the calculation
EDIFF = 1.E-6 ! 1.E-8

ENCUT=500.

#ionic steps
NSW = 0

LSORBIT=.TRUE.

AMIX = 0.2
BMIX = 0.00001
AMIX_MAG = 0.8
BMIX_MAG = 0.00001

LORBIT = 12

NPAR = 2

ISYM=0

ICHARG=11

PROCAR:

PROCAR lm decomposed + phase

please check: for the moment, the number of cores you use must not be larger than the number of atoms in the cell. We'll fix this (probably included in the next sub-release of vasp.5.3)

Dear Admin,
thanks. But regretfully neither one core (12 atoms) solved the problem. Is there another way (maybe from OUTCAR) to know the orbital population of these SOC calculations?
Thanks a lot,
Giacomo
