Principal-Oscillation-Pattern Analysis of Gene Expression

Figure 6

Cumulative distributions of POP amplitudes for selecting the POP amplitude threshold.

Cumulative distributions (Probability(POP amplitude >)) on log-scale of POP amplitudes of all 4598 genes (solid curve) and all genes excluding 344 cell cycle genes identified in experiments (dashed curve). By visual inspection, we see that the gap between two curves starts at POP amplitude ≈ 0.1, which we consider is the cutoff. There are 846 genes whose POP amplitudes are greater than 0.1.
