In uc-bd2k/CLEAN: Clustering Enrichment Analysis

Clustering Enrichment Analysis

Description

Given an hierarchical gene clustering and a list of functional categories, this package performs functional enrichment analysis of all possible clusters and generates files to simultaneously display gene expression data, gene clustering, sample clustering, and functional annotation of gene clustering.
