Good morning, I'm still having problems with the sampleNames for my CEL files. I have already tried to indicate the sample names in ReadAffy function but it does not help: > nm<-c("sampleA","sampleB","sampleC") > data.test<-ReadAffy(widget=TRUE,sampleNames=nm) > sampleNames(data[1]) [1] "C:/Program Files/R/rw1090/rdata/JS1999081101AA.CEL" Could anybody please help me?

You have to list the actual celfile names, not what you want to call them. In addition, you cannot use the widget *and* list the filenames. If you simply want all the cel files in the directory, try this: data.test <- ReadAffy(filenames=list.celfiles()) If you only want a subset, you can call list.celfiles() separately and then subset in the call to ReadAffy() filenames <- list.celfiles() data.test <- ReadAffy(filenames=filenames[some subset]) If you really want to use the widget, you can always change the sampleNames after the fact: sampleNames(data.test) <- sub("^C:/Program Files/R/rw1090/rdata/","", sampleNames(data.test)) HTH, Jim James W.
