 In the destination dir, you should obtain new directories, ``0_before`` and ``1_after`` at the same level as the ``time-sift-block`` directory. These new directories contain all the results natively co-registered.
 
 You can then use `CloudCompare <https://cloudcompare.org/>`__ to compute distance between the ``datasets/0_before/odm_filterpoints/point_cloud.ply`` and the ``datasets/1_after/odm_filterpoints point_cloud.ply`` and obtain this image showing the difference between the two 3D surfaces. Here, two soil samples were excavated as can be seen on the image below.
