Compressing the dendrogram. The output of funcExplorer is compressed by showing only informative clusters (C1 (highlighted with green rectangle), C4) with colorful size-scaled rectangles. The colors denote the domains of significantly enriched functions (p-value≤0.05) in the cluster and are proportional to the number of annotations. The gray bar represents the proportion of annotated genes in the cluster. The enrichment scores used in the cluster detection algorithm are shown for every node below the cluster ID. If the ‘Show sparse clusters’ is selected, the clusters with no significant enrichment are shown with beige rectangles (C5), otherwise they are completely collapsed from the output
