SuperNode Scripts

You can create and save scripts within any terminal SuperNodes using the IBM® SPSS® Modeler scripting language. These scripts are only available for terminal SuperNodes and are often used when creating template streams or to impose a special execution order for the SuperNode contents. SuperNode scripts also enable you to have more than one script running within a stream.

For example, let's say you needed to specify the order of execution for a complex stream, and your SuperNode contains several nodes including a SetGlobals node, which needs to be executed before deriving a new field used in a Plot node. In this case, you can create a SuperNode script that executes the SetGlobals node first. Values calculated by this node, such as the average or standard deviation, can then be used when the Plot node is executed.

Within a SuperNode script, you can specify node properties in the same manner as other scripts. Alternatively, you can change and define the properties for any SuperNode or its encapsulated nodes directly from a stream script. See the topic SuperNode properties for more information. This method works for source and process SuperNodes as well as terminal SuperNodes.
