 **Pipes**: Data is transferred from one module to another using dataflow connections, commonly referred to as Pipes. Each dataflow pipe transfers a specific datatype in SCIRun, denoted by a unique color. Pipes run from the output Port of one module to the input Port(s) of one or more other modules. Ports of the same color correspond to the same datatype and can be connected.
