Must the moving image and the reference image have the same spaing?

si.register_images(I0, I1, spacing, model_name='lddmm_shooting_map', nr_of_iterations=100, use_multi_scale=False, visualize_step=5, optimizer_name='sgd', learning_rate=0.1, rel_ftol=1e-7, json_config_out_filename=('test2d_tst.json', 'test2d_tst_with_comments.json'), params='test2d_tst.json', recording_step=None) I0 and I1 must have the same spacing?Must I0 and I0 be resampled to the same spacing before registration?

Yes, in the current implementation this is required. The images also need to be the same size. This could be changed (and likely should be changed) in a future version.
