Dear bioconductors, i have a problem that presumably concerns my cdfenv installation. I use the zebrafish affymetrix gene chip, and I tried simpleaffy to get some quality control measures. Getting the expression measures with mas5 seems to work fine, but > qc<-qc(x, x.mas5) Gives me an error message: Error in qc.affy(unnormalised, ...) : I'm sorry I do not know about chip type: zebrafishcdf I installed the zebrafishcdf from the bioconductor website but i still get the same error. Then I made the cdf environment myself using the CDF file from Affymetrix and makecdfenv. Unfortunately there is still the same error. Is there something that I missed? Best regards, Georg

Unfortunately simpleaffy is not set up to do qc on the zebrafish chips, which is what the error you get is indicating. For a list of chips that simpleaffy knows about, you can type '.nms' (without the quotes) at an R prompt after loading the simpleaffy package.
