GSEA is one of free tools for analyzing the genome microarray data.It created a molecular signatures database based on the known knowledge of the positions,characteristics,functions,biological meanings of genes,the databse contained many different functional gene sets.Two groups of microarray data,such as experimental and control groups,were analyzed by GSEA,so the enrichment situations of the genes in some chosen gene sets could be learned,even the enrichment had statistic significant or not.GSEA explained the biology information in a different way,and could improve the understanding of related biology processes and drive further research in some areas.
