The process I'm studying is a sort of phase transition in solid state: I start from a bulk unit cell and I finish with another bulk unit cell with a group of atoms rotated by a given angle. The problem is that the cell parameters change in the process.
not possible.

Then, in the BAND section, only the xyz of the images are included, therefore I suppose they all share the same cell of the first point. Is there a way to do a NEB calculation with, let's say, 12 images, adding the starting and finishing points with different unit cells, then allowing CP2K to create the remaining images by interpolation (also interpolating the cell parameters) and then optimizing the bands? As far as I know, this thing is possible with VASP.
