The network is shown in Figure .

Figure: Network to display a sequence of slices in a data cube.

• To specify the data cube to be read double-click on the `Import' module and follow the instructions in Section .

• To specify the axis to which the slice is perpendicular double-click on the `Integer' module at the top of the network. The permitted values are 0, 1 and 2 for the $x, y$ and $z$ axes respectively.

• To specify the range of slices to be shown double-click on the `Sequencer' module. A control panel with controls similar to (and corresponding functions to) the buttons on a cassette tape deck appears. Click on the ellipsis (`...') button and a further window appears allowing you to specify the first and last slice to be extracted (and the increment between slices). For a cube with $n$ elements along the chosen axis the permitted values are 0 to $n-1$.

  Finally, once you have chosen the required range, click on the play button (` $\triangleright$') in the original `Sequencer' window.
