Results of iterative clustering with dataset I. A. Number of clusters as a function of the number of iterations of clustering dataset I with a p-value cutoff of 10^-4. B. Percent of genes residing in biologically coherent clusters as a function of iteration cycle. Data are shown for the percent of clusters with a minimum of biological coherence of p-value less than 10^-3 and of p-values less than 10^-4. C. Average p-value over the entire set of clusters as a function of iteration cycle.
