Hi!

I used gage in order to perform a pathway enrichment analysis, using a table with KO numbers. Œs it possible to retrieve information about the abundance of the differential pathways? Because I have only KO numbers in my table (without all the kegg identification levels), so I don't know how to collapse them to pathways and find out how abundant is a specific pathway in each sample.

Thanks

Francesca

If you want the summary expression perturbation for each pathway in each sample, you can check the stats element of the gage analysis results. Following the example in the main gage tutorial, you can do: … > gse16873.kegg.p <- gage(gse16873, gsets = kegg.gs, + ref = hn, samp = dcis) > names(gse16873.kegg.p) [1] "greater" "less" "stats" > head(gse16873.kegg.p$stats) …(a matrix with pathway as rows and samples as columns) > str(gse16873.kegg.p$stats) … HTHs, Weijun
