Figure 5:

Examples of biologically relevant genes with damped harmonic oscillations missed under standard circadian analysis. Circadian proteins casein kinase II subunit β−2 (5a), alpha/beta hydrolase protein (5b), and F-box LRR repeat-containing protein 2 (5c) display a damped rhythm and are identified as rhythmic by the extended harmonic oscillator in this analysis but not by JTK_Cycle using identical statistical tests and significance. The figures provide both the experimental data (black) and the fitted models (blue).
