Gsea phenotype labels
WebThe expression data can be loaded in three different formats: gct (GSEA file type), rnk (GSEA file type) or txt. The expression data serves two purposes: Expression data is used by the Heat Map when clicking on nodes and edges in the Enrichment Map. Gene sets can be filtered based on the genes present in the expression file. WebOct 5, 2024 · Answer. In GSEA the point is that the gene set (and not the genes per se) is differentially expressed. This can even be in a mixed model where some genes in the gene set are up (maybe not ...
