"No gene can be mapped" when running enrichPathway

[RuiyangLiu94]

Hi,

Thanks for establishing the R-based Reactome tool.

I want to do a pathway analysis based on a list of mouse genes, but when I tried the function enrichPathway, an error pops out as "--> No gene can be mapped.... --> Expected input gene ID: 5660,5695,23295,25915,161,3433 --> return NULL..."

I used the entrez id associated with the geneset as the function input; I also tried to upload this entrez id list to Reactome website for analysis. For the web-based analysis, there are some results popping out. Therefore I am wondering what could be the reason for the error? Is it because no pathways are found or because the entrez id from mouse are not accepted by ReactomePA?

for reference the code I used to run pathway analysis is: x <- enrichPathway(gene=geneset_entrez,pvalueCutoff=1, readable=T)

Looking forward to your reply!
