The Pipeline need the user to explicitly specify that two different modules are connected. Two modules are automatically connected if one of each of their arguments bind to the same resource. That is, if one module has the same input as the output of another module, the Pipeline automatically knows that the two modules are connected.

There are two ways in which the GUI allows for two modules to be connected.

• An argument from each of the modules are bound to the same resource
• In the GUI, click on an argument, and drag the mouse to another argument that you would like to connect. The application will automatically ensure that they bind to the same resource. Note: the GUI will not allow you to connect two arguments if they have incompatible datatypes.

Note: multiple modules can be connected by all binding to the same resource.

an example of a successful connection between two modules

If you want to undo the connection, simply right click on either parameter the module is connected to (square icon on edge of module) and click "Unbind".
