 Other displays also show outputs from the deep learning module. Hovering over data units in the click display will, for example, show deep learning prediction values. The spectrogram will also show deep learning detections as translucent blue boxes (these must be selected in the right click menu). 
 
+### Symbol Manager
+
+The deep learning classifier has a symbol manager that is used throughtout different PAMGuard displays. The symbol manager can either display deep learning detections by the prediction values of a particular class or colour the output class with the highest prediciton class. Colouring by a prediction value requires the user to select which output class they wish to display - all detections are then coloured by the output prediction values for that particular class via a selectable colour map. If colour by class is selected then each detection is coloured by the class with the maximum prediction value. The colours for each class are selectable.

+### Data selector
+
+The deep learning classifier has a data selector which is utilsied thorughout PAMGuard (for example for exporting detections, generating clips, showing on displays). The data selector allows users to filter detections based on a minimum prediciton values for different output classes. Classifiers with multiple classes can have different minimum predicitons values assigned to each class. The user interface allows user to use a slider to dynimically change the minimum prediciton value. The lock button clamps the minimum prediction values of all enabled output classes together.

 ### MATLAB
 
 The easiest way to export to MATLAB is to select the desired units in the time base display, right click and select the MATLAB icon. Data units will be exported to a .mat file as list of structures which is then saved to the clipboard. This file can be saved and then dragged into MATLAB to open.
