The NEB.X in Quantum Espresso contains a way to manually select an image file that will climb to the peak of the energy curve. CI_scheme needs to be set into 'manual' instead of 'auto':

My question is how does its syntax look like? For example, I set 7 images and I want image 3 to climb, will this portion of the input file look like:

CLIMBING_IMAGE

3

Or are there anything else to add? I can't seem to find any example in the internet using the CI_scheme='manual'.
