Dendrogram of average-linkage hierarchical clustering for a gilad dataset. Dendrograms for a total of 26 ranked gene lists when using a default floor PDEG value setting (= 5%) are shown. The correlation coefficient is used as a similarity metric; the left-hand scale represents (1 - correlation coefficient). Each gene list is denoted as an “XXX-YYY” combination (the normalization method XXX followed by the DEG identification method YYY). Gene lists having iteration numbers on the left side correspond to cyclic results.
