Figure 1. Illustration of quantization for ABA gene expression data.

Figure 1

(a) A rectangular grid derived from the level 5 substructures. Left: forebrain (anterior), right: hindbrain (posterior), top: roof (dorsal), bottom: floor (ventral). (b) The spatial expression profile of Arx at E11.5. Red and green blocks denote substructures with high and low expression levels respectively. White blocks denote either non-existing substructures or missing data. (c) The number of expressed regions obtained from the quantized Arx expression data with varying threshold values. (d) The quantized Arx expression data with threshold 0.2384.
