Hello,

I have been pointed out A: How to use topGO and KEGG with de-novo species that is possible to use how to use "non-standard" species for KEGG / GO analysis in limma? to do any analysis, including KEGG or GO analyses of a new species.

How is it possible to create an annotation database using annotationHub() or by supplying the gene.pathway data.frame directly for my non-model species?

Thank you in advance.

One obviously needs a mapping between your organism's genes and the pathway that those genes belong to. Where that mapping comes from depends of course on the organism, and probably you are in the best position to identify this source. Minimally, adding, as a COMMENT, the organism that you are working on is essential for others to help you make progress here.

It is a non model plant genome and I ran edgeR and I have a the following genome annotation file:
