Figure 1.

Normalized average difference (Avg Diff) of one pair of replicate arrays for each experimental condition in a log₁₀ scale. (a) heat-shocked Otx2; (b) heat-shocked otd; (c) heat-shocked wild type; (d) wild type. Only probe sets with positive values in both arrays are used. The central line is y = x, and the flanking lines indicate the difference of a factor of two.
