A pattern of temporal activity selected in an application that supports both clustering and visual queries. A known pattern of temporal activity has been selected in the visual query view (bottom) and with their positions highlighted using arrows in the cluster view (top). Despite the fact that the genes share a similar profile over an interval of the data time-frame, more dominant patterns of expression over the remainder of the time course cause the genes to be assigned to different clusters (this is not, however, the case for all genes since some genes are close enough to each other in the cluster view that the arrows showing their position overlap).
