ROC analysis of the S-phase cluster of Cho et al. (1). (A) ROC curve (left) shows the overlap between this cluster of 74 genes and genes from all other clusters in the time-course analysis [383 genes in total, selected by inspection by Cho et al. (1) for cycling behavior]. The area under the ROC curve is 0.82. The area under the curve highlighted in green demonstrates selection of genes from S phase that overlap with other clusters least. At the shown distance threshold, 66 genes from the Cho determined S-phase cluster are selected, and the overlap with only non-S-phase genes. (A) Right: correlation distance histograms illustrating the distribution of distances to the center of the S-phase cluster for non-cluster members (bottom/blue) and for all S-phase cluster members (top/red). (B) Expression trajectories for the 74 genes in the S-phase cluster, highlighting in green cluster members represented by the green highlight in (A). (C) Expression trajectories for all genes outside the S-phase cluster of the Cho clustering highlighting in green non-cluster members represented by the green highlight in (A).
