Claire,
You can try GAGE/Pathview for non-model organisms. They support ~3000
KEGG species. However, you need to have the full dataset instead of a
pre-selected list of differentially expressed genes.

Hello
I would like to run an hypergeometric testing on KEGG terms for non-
model organism. When it comes to Goterm I always use Gostats where I
can enter my "universe" list and then my "target" genes and it works
really well.
However, when it comes to Kegg pathways, I tried to use go stats again
but it's based on the kegg.db which is outdated and as a result I get
the following error:
"Loading required package: KEGG.db
Failed with error: ???package ???AnnotationDbi??? 1.24.0 is loaded,
but >= 1.25.15 is required by ???KEGG.db??????
In addition: Warning message:
package ???KEGG.db??? was built under R version 3.1.0
Error in .testKEGGFrame(x, organism) :
None of elements in the 1st column of your data.frame object are
legitimate KEGG IDs."
Does anyone have any recommendations for Kegg enrichment analysis for
non-model organism and /or how to do an hypergeometric test with R
directly?
Thanks a lot for your help
