Dear Prof. Graeme and others,

My system for NEB calculation is composed of 200 atoms and the z-direction is vacuum. My INCAR file is as follows:
PREC = Normal
ENCUT = 400
IBRION = 3
ISIF = 2
POTIM = 0
NSW = 100
ALGO = Normal I(blocked Davidson)
NELM = 100
NELMIN = 5
EDIFF = 1.0e-05
EDIFFG = -0.01
ISPIN = 1
INIWAV = 1
ISTART = 0
ICHARG = 2
LWAVE = .FALSE.
LCHARG = .FALSE.
ADDGRID = .FALSE.
ISMEAR = 0
SIGMA = 0.05
LREAL = Auto
IMAGES = 1
SPRING = -5
LCLIMB = True
IOPT = 2
ICHAIN = 0
ISYM = 0
NPAR=1

When I finish the neb calculation, I use nebbarrier.pl to generate the distance, energy and force. However, the result is as follows :
0 0.000000 0.000000 0.000000 0
1 0.000000 1.421456 -0.074255 1
2 0.000000 -3.524564 0.000000 2

All the distances are 0. How should I fix this?

Thank you very much.

You probably do not have our vtstcode linked into vasp. Check the OUTCAR for a line with VTST in it.

Dear Prof. Graeme
The information in OUTCAR shows that:
VTST: version 3.1, (03/28/14)

CHAIN: initializing optimizer

OPT: Using Conjugate-Gradient optimizer
OPT: CG, Init
OPT: CG, FDSTEP 0.005000
OPT: CG, MAXMOVE 0.200000

In the OUTCAR file, the last line which contains "distance" is as follow:
NEB: distance to prev, next image, angle between 0.781046 1.021208 112.549589

I have found the problem, I have not added the "dist.pl" file in the directory.
