Genes not mapping to pathway!

Hi, does anyone know any potential causes for following issue? I am following this workflow, and I don't get my genes mapped to any of the output pathways. Example is from one. Another thread I have going on here as well.

Error:

Getting gene ID data from KEGG...
Done with data retrieval!

[1] "Downloading png files for spo03013, 1/1 pathways.."
No of the genes or compounds mapped to the pathway!
Argument gene.idtype or cpd.idtype may be wrong.

As the error says the gene.idtype you selected is different from the one you used as input. If you are using gene symbols you should specify gene.idtype="SYMBOL" inside the pathview() function.

Thanks Gian, I changed it to gene.idtype="KEGG" as I was advised and it worked. Thanks though!
