Hello, I'm trying to use GOSim with yeast but with no luck. The function "setEvidenceLevel(organism="yeast")" doesn't seem to work. Using the org.Sc.sgd.db library, I obtain a long list of GO terms for "856452" Yet, getGOInfo("856452") yields, No GO information available for these genes! Any help would be greatly appreciated.

Hi Fred, I can't speak to what is happening with GOSim:::getGOInfo. But if you are using the most recent version of bioconductor, then you could also do this kind of lookup like this: library(org.Sc.sgd.db) ID = "YHR055C" select(org.Sc.sgd.db, keys=ID, cols = c("GO","ENTREZID"), keytype="ORF") Marc On 05/22/2012 05:31 AM, Fred Hoffman [guest] wrote: > Hello, > > I'm trying to use GOSim with yeast but with no luck.
