Itried to do neb calculation as suggested to me in the forum but Ihave got this message error :

and the INCAR file is as :
ISTART = 0 ; ICHARG=2
ISMEAR = 1 ; SIGMA = 0.2
LORBIT=11
LREAL=.TRUE.
PREC = High
IALGO = 48
ENCUT = 400
ISPIN=2
SPRING=-5
IMAGES=8
IBRION=1
Can any one tell me what the problem?
Thanks for your suggestion.
Neb calculation fails

I don't really see any problem with the POSCAR file but we recommend setting the element symbols in the top line for our scripts to work properly, like:

As dwyuan points out then files that are altered on a window$ machine can have trailing characters at the end of each line when ported to a UNIX/Linux system, e.g. the EOL or NUL character. These need to be stripped off. In a tcsh shell, this is how I strip the NUL character (000 in Oct) from files (ascii.tcsh):
#!/bin/tcsh
foreach a ($argv)
echo $a
tr -d "\000" < $a > ascii_tmp ; mv -f ascii_tmp $a
end
then I run ascii.tcsh <input_files> .
Also, if you are using our implementation of NEB then the initial and final configurations should be in directories 00 and 09 (assuming 8 images as you seem to be using), respectively. If you are using the VASP implementation of the elastic band then the question is more appropriately directed to the offical VASP community forum,
