Directories contain the optimized images in the NEB calculations (subdirs 01..04) together with the reactant and the product configurations (subdirs 00 and 05).
Image 03 corresponds to the barrier configuration in all cases.
Energies.dat files include the energy as a function of the image number for the various functionals. 
The INPUT directory contains example VASP input files employed to perform NEB calculations for a given functional.
