-Yes. If you select //true// in the "Top Down Multi-Class" option, you must create another node in the same level with a corresponding opposite name, with prefix "n-". For example, if this class name is "MyClass" the opposite class name will be "n-MyClass". Hypothesis discarded by this operator will be classified as "n-MyClass".

+**Processing sequence**
+  -Read user input shape file.
+  -Generates the intersection between the loaded shape file polygons and the operator execution area.
+  -Using the intersection result generates a set of intermediate hypothesis of "MyClass" and the opposite class "n-MyClass", as describe above.
+  -Apply the user decision rule (using the supplied training set) over the intermediate hypothesis set.
+  -Generate the output hypothesis from the decision rule result.
