Abstract

Selection of 15 clusters of gene expression in EB, apical-LB, and basal-LB in different locations on the P/D limb axis. Join distance (1-Pearson’s correlation, y-axis) plotted as a function of number of clusters. After fifteen clusters, join distances reach an asymptote, suggesting that using more than fifteen groups provides little additional information (small distance indicates separating similarly expressed genes), while using more than fifteen clusters results in joining dissimilar groups (high distance).
