Thanks, @emmanuel-ferdman. Could you please also add this test or a similar one in test_image.py?

    def test_different_shape(self):
        path_1 = self.get_image_path('im_shape1', shape=(5, 5, 5))
        path_2 = self.get_image_path('im_shape2', shape=(7, 5, 5))

        with pytest.raises(RuntimeError):
            tio.ScalarImage([path_1, path_2])
