Figure 8.

Heatmap of probe-level data for genes selected by each filtering method. The probe-level data are shown for the differentially expressed probe sets uniquely identified by the A/P filter (388665_at), the variance filter (1380348_at), and by the PVAC filter (1389772_at). For each probe set, the probe-level data (on each row) were scaled to mean 0 and unit variance for displaying in the heatmap, with the groups labeled as 1 and 2 and the probe identifiers shown on each row. The red and green colors represent high and low probe intensity, respectively.
