Hi all, I have a naive question regarding the heatmap of the top 50 features for each phenotype in dataset generated by GSEA. I wonder is it also called differentially expressed genes? The heat map showed some genes are clearly up- and down-regulated, however those genes are not differentially expressed when I compared with the DEGs result I got from EdgeR. Noted, I used normalized count value (CPM) from TMM method in edgeR as input for ranked gene list in GSEA. Please help me elaborate, thank you in advance!!!
