Hi, I have a standard cell which I would like to rotate. I would like to rotate it in such a way such that when I define some plane in the unrotated cell [hkl] that this same plane corresponds to the  plane in the rotated cell. I essentially want to keep the same unit cell, just rotate the atomic positions inside it so the cleavage plane I have defined corresponds to the face of the cell. How could I go about doing this? Any help, even just a link to more info is appreciated!
