Table 1. Effects of changes in gene group size and composition on RS and GWO values.

Change in gene group	Effect on RS	Effect on GWO	Other effects
Reduced number of genes (Fig. 4)	Minimal	None	Increase in statistical cut-off levels
Increased number of genes (Fig. 5)	Decrease	Decrease	Increased computing time and memory usage
Imperfect gene selection (Fig. 6)	Decrease	Decrease

This table summarizes the effects of changes in gene groups on RS and GWO values, as described in the text.
