Changing Parameter Values in Kepler. This is a screenshot showing the changing of a parameter value in a workflow. Parameter names and values are displayed clearly on the Kepler canvas. Parameters may be easily moved into groups and font type, size, and color can be manipulated to provide visual cues as to importance or group relationships. Parameters are changed by simply clicking on the parameter. As shown here, clicking on the parameter indicates the parameter in question with a small yellow box and produces a text box in which the new parameter value may be entered. The displayed workflow is the gene expression workflow shown in Figure 5. See RESULTS for details.
