    8 Open an image UVMAT_DEMO06_displacement. This is a target pattern used to measure the displacement of a plate vs time. Observe the motion by scanning the images.
     8Open an image 'UVMAT_DEMO05_displacement/images'. This is a target pattern used to measure the displacement of a plate versus time. Observe the motion by scanning the images.

    10 Make a mask to remove the outer part in the PIV processing, like explained for tutorial 5, or introduce the mask provided .ref (selecting the upper bar button .. in uvmat)
