How to specify NEB and cNEB?

In the vasp guide, http://cms.mpi.univie.ac.at/vasp/guide/node140.html, it says that SPRING=0 is the NEB method, but this webpage, http://theory.cm.utexas.edu/vasp/neb/, says that negative value for SPRING turns on nudging. Which is right?

How can one specify cNEB? LCLIMB=.TRUE. is that enough? I've done both NEB and cNEB calculations now, and there are no difference. Is cNEB a default in NEB-calculations in vasp now?

Hi,

I dont think VASP supports CL-NEB. Why dont you use VASP TST tools?

SPRING tag refers to the spring force between images and negative value turns on nudging.
