The easiest is probably to choose the channel and then run Reduce
Dimensionality... unchecking the channels, keeping the original image. In
effect you'd duplicate just that channel. In macro code:

        // make the second channel the active one
        Stack.setChannel(2);
        // duplicate just that channel
        run("Reduce Dimensionality...", "slices keep");

Just paste your macro after that, or run it with something like
runMacro("/Users/hoeppner/my-macros/magic.ijm");

Ciao,
Johannes
