Hello everyone

I am trying to use this package graphite for pathway analysis from gene expression data of Rice( Oryza sativa) . However, I cannot retrieve the pathways from kegg using this package. I am using this code osa <- pathways("Oryza sativa" , "kegg")

Firstly can it be used for organisms other than listed in pathwayDatabases() ? If so, how to do that ?

Thanks in advance.
