Hi, Yihuan: Check the following link: http://www.broad.mit.edu/gsea/wiki/index.php/Msigdb_may_2006_release_n otes and you will find KEGG has been built into MsigDB of GSEA. So, if your purpose is GSEA analysis, the only thing you need to do is map your ACC number to Entrezgene id. John's suggestion is also helpful if you try to use KEGG package in BioC. BTW, I recommend you use desktop version of GSEA since it takes me a lot of trouble to change the codes of R's version ( I believe there is a bug and report it to GSEA group already and I believe they are working on that now).
