Given the clusters, the importance score of each feature is calculated. This is defined as the maximum pairwise symmetrized Kullback Leibler divergence. These scores reflect which features are most discriminative between clusters.

cghdata.regioned |
A |
dendrogram |
Determines if and how the row dendrogram should be computed and reordered. Should be a dendrogram as returned by |
nclusters |
An integer with the desired number of clusters. |
A matrix
whose first five columns contain annotation information and the sixth the region's importance score.
