Updating may not solve your problem in this case - simpleaffy only has the control probe information for some common-used chips stored in it's environment; it doesn't take them from the cdf. There have been quite a few posts about this on the Bioconductor list... so many that it would be useful to put some sort of caveat in the help files for affyQCReport and simpleaffy! At any rate, check out my previous post and the possible fix referenced in it: https://stat.ethz.ch/pipermail/bioconductor/2007-January/015575.html Cheers, Jenny At 10:32 AM 2/6/2007, Seth Falcon wrote: >Hi Emmanuel, > >"Emmanuel Levy" <emmanuel.levy at="" gmail.com=""> writes: > > The reason is that the package of the chip I use (celegans) is not > > found in .qcEnv > > > > Do you know why it is not added when I load the celeganscdf library? > > Shall I add it myself?
