Expression profiles of the classes in typical completely synthetic datasets with four repeated measurements. (a) Low noise level; (b) high noise level. For each class, the log ratios are plotted against the experiment numbers, and each class is shown in a different color. There are four sine (periodic) classes with different phase shifts and two linear (non-periodic) classes. Only four (out of six) classes are shown in (b) for clarity.
