Analysis of the reproducibility of Actichip data using a hierarchical array clustering. The array data from ten replicates were clustered in the Acuity program using a hierarchical procedure based on the average linkage method and Pearson correlation coefficient. The experiments are grouped on the resulting dendogram according to their relative degree of similarity. Experiments and dye swaps 1 to 3 and experiments and dye swaps 4 and 5 were performed at two different time periods.
