Hello,
What does it mean when all the intermediate images are having negative energy and thus the barrier is also negative? what should be done in this case?
Thank you.

Re: Negative energy. barrier
I came across the same situation a few days ago. In my case, I redefined the reaction pathway (subdivided it) because I noticed that there were local minima between the starting and ending points.
Did you also use the script nebbarrier.pl to generate the image energies?

This is usually due to having different computational settings for the endpoints as compared to the neb images.
