Hi All, FYI, I noticed that MTHFR, a key gene of the folate pathway, is not in the pathway 00670 "One carbon pool by folate," though it certainly should be. For example, this code library(Biobase) library(hgu133a) library(KEGG) IDs=get("00670", env = hgu133aPATH2PROBE);IDs as.character(multiget(IDs, env = hgu133aSYMBOL)) fails to pick up these three probe sets for MTHFR: 206800_at MTHFR 1p36.3 5,10-methylenetetrahydrofolate reductase (NADPH) 217070_at MTHFR 1p36.3 5,10-methylenetetrahydrofolate reductase (NADPH) 217071_s_at MTHFR 1p36.3 5,10-methylenetetrahydrofolate reductase (NADPH) Tom

I will do another build next week to fix the problem. I tried your code against the release version (1.5.1).
