Running VASP 4.6 with opteron / intel woodcrest 64 bits proc. (IBM / HP), I get the following message:

Error reading item 'ISPIN' from file INCAR.
Error code was IERR=5 ... . Found N= 0 data

So I can not perform spin polarized calculations althought I know it has already run correctly with the following INCAR file on an other calculator

Here is the INCAR file:

Electronic Relaxation
ALGO = Fast
LDIAG = T
LREAL = A
ENINI = 250
ENCUT = 450
NELMIN = 8
ISPIND = 2
ISPIN = 2
MAGMOM = 121*1 2 1 1

DOS related values:
ISMEAR = 0
SIGMA = 0.1


Ionic Relaxation
IBRION = 2
NSW = 201
ISIF = 2
POTIM = 0.5


If you have any idea to solve this problem .....

Thanks very much

ISPIND is not to be read from the INCAR file, so please delete this line.
If the error persists, ther may be a hidden character in the ISPIN line which makes the input line invalid. please check with 'strings INCAR'
