Figure 1:

Overview of the clusters selected for further analysis. We grouped the 1673 genes present in the 23 clusters that we selected for further analysis (see methods) and hierarchically clustered them together to demonstrate the relationship between the different expression patterns. Approximate extent of clusters displayed in more detail in Figure 3, Figure 4 or Figure 5 are indicated on the right (note that some genes are in more than one cluster so these boundaries are only approximate). Each row represents one gene or clone and each column represents one experiment. Yellow bars represent induced measurements, blue bars represent repressed measurements and gray bars represent missing data.
