I would like to use ChIPseeker to get GO and KEGG enrichment analysis of my ChIP data (mouse cells mm9), but I am getting an error I don't know how to fix. I have my peak files as BED files and have been able to sucessfully get them read into the package using rtracklayer. I have also been able to plot the annotation features just fine. When I try to use the function "enrichPathway", the system gives me an error that it's looking for the human annotation data which is a problem since my samples are murine. I have looked at the information available but the arguments aren't listed so I don't know how to correct this.

If someone can help me out, I would be very grateful.

Many thanks, juli







peakAnno.d3TCR.p300 <- annotatePeak(d3TCR.p300, tssRegion = c(-3000, 3000), TxDb = TxDb.Mmusculus.UCSC.mm9.knownGene, annoDb = "")

gene.d3TCRp300 <- seq2gene(d3TCR.p300, tssRegion = c(-1000, 1000), flankDistance= 3000, TxDb=TxDb.Mmusculus.UCSC.mm9.knownGene, sameStrand = FALSE)

You need to have installed.
