Hi Everybody, I need your suggestion for the package to use so as to perform gene set enrichment analysis. I know the analysis directly relates to GSEAbase package but I not sure its the right one for the analysis I have in my mind. I need to make: 1. Heatmap of gene set enrichment of specifically enriched genes against various biological process and diseases categories/gene sets 2. Heatmap of gene set enrichment of specifically enriched genes against tissue specific gene sets I have microarray data analyzed for 10 timepoints using 'affy' and 'limma'. The results have 'probeId's and 'Gene Symbols' as identifier. My question is how do I approach and which package should I use? Thanks AK
