Thanks a lot for your reply. I have attached the iopt=7 and iopt=2 calculations with 5 images.
I have tried both fire and aggressive optimizer, and both of them have the same problem.

Energy and coordinates in NEB are oscillating
Dear all,
I am using the NEB to calculate the TS. I use 5 images. The energy of the 3rd image is just oscillating and the XDATCAR
shows that the atoms are just oscillating back and forth. After 375 steps, it is still oscillating and not yet converged.
The parameters in INCAR are:
IMAGES=5
