Different ways of representing the cyclic genes for the alpha experiment in Spellman et al.. (a) is the standard heat map using average-linkage hierarchical clustering in MeV, shown here for comparison. (b) is the result of 2D nMDS. The profiles for all the genes in each grid cell in (b) are shown using lineplot in the corresponding grid cell in (c). (d) shows heatmap1 in which the angular positions of genes in (b) is used to reorder the rows in (a). (e) is circularmap using the angular positions of points in (b).
