Dear all,


I am trying to look at a relatively old mouse data that was taken using Expression Chip v6.1.1. The problem came I when I tried to convert Probe IDs to gene names. Probe IDs are, for example: 10243, 10280, 10575, 20048, ..., 102900072, 102900075, ...


I tried an old keys/mapIds way using 3 packages: illuminaMousev1.db, illuminaMousev1.1.db, illuminaMousev2.db and none had Probe IDs similar to what I got from GEO file


As an example of how I did it:



ks <- keys(illuminaMousev1.db)

annData1 <-, function(x) mapIds(illuminaMousev1.db, ks, x, "PROBEID")))


I eventually (possibly) succeeded using 

genes <- probeID2nuID(probes, lib.mapping = "lumiMouseIDMapping"[,"Symbol"]


from lumi (I was using lumi for reading/normalizing anyway), but when I started investigating duplicate gene entries and presumably transcript variants, I felt a need to double check the conversion. Does anybody have a suggestion?


By the way, when I try


(380091 being a probe ID for one of genes with name repeated multiple times and with different, according to google, transcript variants) I get

Error in (function (classes, fdef, mtable)  : 
  unable to find an inherited method for function ‘columns’ for signature ‘"function"’


Thank you

Hi Smt8n,

Those look to me to be ArrayAddressIDs that are in illuminaMousev1p1.db. An (inelegant) approach to extracting them would be:



fullanno[fullanno$ArrayAddress %in% c(10243, 10280, 10575, 20048, 102900072, 102900075),c(2,12,13,16)]

I hope that helps.
