- For N genes in a cluster, N(N-1)/2 pair-wise Pearson's correlations on expression were measured and their average was calculated. Next, N genes were randomly selected from a set of ~18,000 human genes and the average pair-wise correlation was calculated from the random gene set. The distribution of the average pair-wise correlation of random genes was re-estimated 1,000 times to generate a null distribution of the average pair-wise correlations. A p-value for each cluster was estimated by counting the number of random gene sets for which the average correlation is larger than the cluster correlation. *No random gene set that exceeded the cluster was found in 1,000 repeats.
