Thanks for this great tool for enrichment analysis.

I have successfully used clusterprofile to perform GO and KEGG analysis given human entrez ids.

However, for Arabidopsis, I have encountered a problem with bitr_kegg when transferring IDs. 100% of these IDs are failed to map.

Ps. When using these entrez IDs for GO enrichment, no warning message encounted, assuming 100% map.

Edit1: transfer dataframe to vector to exclude R usage problem.

Thanks!
