Editing TkMadagascar (section)

=== Linking Flows === 

One of the nicest features of Madagascar is that programs can pipe their output to other programs, greatly reducing the need for intermediate files.  This functionality is fully supported by tkMadagascar.  To link two Flows, right click on the flow that you want to link to another Flow, and select ''' Link'''.  The cursor will change to a cross-hair to indicate that you are in '''Link''' mode.  Once in '''Link''' mode, click on the Flow that you want to link to.  The Flow that is selected for linking is assumed to have desired output for the Flow that you right-clicked on.  

Once Linked, the two Flows move together, their borders change color, and their input and output parameters are automatically changed to reflect the fact that one is piping into the other.  The border colors change as follows:
Flows  become light gray,
Plots become light purple,
Results become light blue.

To '''Unlink''' a Flow, simply '''right-click''' on the Flow you wish to unlink, and then select unlink.  The Flow will be detached.  The other Flows in the Linked Flow will be detached as well, or placed into separate Linked Flows.
