In this tutorial, we explain what gene set enrichment analysis (GSEA) is and what it offers you. We show you how to run the analysis on your computer and take you through how to interpret the outputs. The tutorial also covers leading edge analysis and analysis of gene networks with Cytoscape.
*** Editors note: If you are having trouble loading your gct file, you should save it as .gct.txt rather than just .txt
