Hi,
When I read the Affymetrix HGU133 spike-in data using
spikein<-ReadAffy() I get no problems.
From a different directory, with rgu34a CEL files,
after trying chip<-ReadAffy(), I get the message
Error in validityMethod(object) : No slot of name "phenoLabels" for this
object of class "phenoData"
I never used to get this message. I have installed the
developers versions of the software but I still get the problem.
What is going wrong?
Best wishes and thanks in advance,
Harry
