Hi,

I understand GSEA is typically run with an expression dataset. If I have just a list of genes, I can run compute overlaps with the MSigDB database online:

http://software.broadinstitute.org/gsea/msigdb/annotate.jsp

However, I am wondering if I can compute overlaps in MSigDB datasets locally through a command line for a list of genes. I want to do this because I have tons of such datasets (only genes) which I need to query for overlaps with MSigDB. Has anyone done this?

Thanks.

What you need is an implementation of Fisher's exact test and some sort of matching algorithm.

I've never used it in a separate tool, but you probably can apply some of the code used to calculate GO enrichments, or just write it yourself - should be pretty easy.
