Launch Aspire (if it's not already running). See:
To add a Saga Python Bridge application drag from the Application Saga Python Bridge rule from the Workflow Library and drop to the Workflow Tree where you want to add it. This will automatically open the Saga Python Bridge window for the configuration of the application.
In the Saga Python Bridge window, specify the configuration information.
Example:
Once you've clicked on the Add button, it will take a moment for Aspire to download all of the necessary components (the Jar files) from the Maven repository and load them into Aspire. Once that's done, the application will appear in the Workflow Tree.
For details on using the Workflow section, please refer to Workflow introduction.
