-Other example: for the perovskite structures (shipped with Tilde), extract the distortion of the MO6-octahedra wrt cubic phase (in Euler angles) and detailed calculation info. Here the **-i** switch shows additional details and the **-m** switch invokes **perovskite_tilting** module (see **apps** folder):
