Example dataset and results after applying randomization methods of this study. The original dataset is a simulated expression matrix of 10 genes and 20 time points. The first 5 genes are cyclic and the values for the last 5 genes are randomly drawn from a normal distribution, as can be seen from the heatmap of the original dataset. Randomized datasets are illustrated with a simplified chart showing the basic operating principle and a result dataset shown as a heatmap.
