Shabtai et al. Ideal and random outcome of TAG4 Microarray dataset cluster. Expected results of an ideal outcome and a random outcome. The left column displays the cluster of experiments where the labels are the dates on which the experiment was performed (a, c). Adjacent identical dates are displayed in a red rectangle to indicate when clustering occurs by date. The right column displays the cluster of experiments where the labels are the chemical compound that was used for each experiment (b, d). Adjacent identical chemical compounds are displayed in a green rectangle as shown in the legend, to indicate when the same chemical compounds are clustering together. The ideal result shows that experiments, performed using the same chemical compound, cluster together according to chemical compounds, where each cluster can be seen in a green rectangle (b). The ideal result also shows that the experiments cluster by date only when they were performed using the same chemical compound (a). The random score did not cluster any of the experiments according to chemical compound (d), and clustered experiments by date only by chance.
