The GUI of the Raven tool suite consists of a main bar and additional four components that divide up the screen. On the upper left is the main panel, that allows the selection and application of different algorithms. The output panel is situated on the lower left and is used to display textual outputs. On the upper right one can find the so called repository panel. Here all objects that are currently accessible are listed. By clicking on one of these objects a detailed description of the object is given in the panel on the lower right of the GUI.
