Hi All The platform for GSE4137 is "Custom cDNA 41,424 clones", and organism is human. I tried the code which you mentioned,but gives me error:- get("AA502230",revmap(org.Hs.egACCNUM)) Error in .checkKeys(value, Rkeys(x), x at ifnotfound) : value for "AA502230" not found Is this error coming becuase i am using it for cDNA platform? Regards

This particular error is due to the fact that the "AA502230" (which is the accession for an entry from dbEST) is not cross-referenced to an Entrez GeneId, see: http://www.ncbi.nlm.nih.gov/nucest/2237197?report=genbank Regards, Hans On 01/04/2012 06:22 AM, Reema Singh wrote: > Hi All > > The platform for GSE4137 is "Custom cDNA 41,424 > clones", and organism is human.
