Hello,

I am working on an affymetrix project , my data are files.cel, and i am using oligo package , my script is

celFiles<-list.celfiles(dir,full.names=TRUE)
rawData<-read.celfiles(celFiles)
library("pd.hugene.2.1.st")
ppData<-rma(rawData,target = "probeset")
mat<-exprs(ppData)

the row names of my matrix gene expression (mat) are

"16650001" "16650003" "16650005" "16650007" "16650009" "16650011" "16650013" "16650015" "16650017"

how can i replace this rownames by the probe ID of my data, like (12547_at)

 

Thank you
