Why is number of geneset present in MSigDB C2:CP:KEGG geneset different from the original KEGG pathway?

Question

[mariet1051]

Hello all, I was trying to do GSEA and then realized that MSigDB is showing only 186 genesets from C2:CP KEGG (http://software.broadinstitute.org/gsea/msigdb/collection_details.jsp#C2) while ~260actually genesets exist in the original KEGG pathway. Why are many genesets missing? And from where can we download the complete KEGG geneset (human)? Thanks in advance!

There may be many reasons, but best not to speculate. I recommend that you contact the GSEA team: http://software.broadinstitute.org/gsea/contact.jsp
