Hello everybody, does anyone know, where I can find the correct values for the qcdf file of the droso[hila genome 2 microarrays? I am running the qc plot analysis using qc() from smpleaffy/affy packages. As I needed to set manually the environment I just took the human qcdf file from the R repository and used it to run my qc(raw.data) > setQCEnvironment(array="drosophila2cdf", path="~/Luke/Microarray") # set environemnt for the right array cdf > qc = qc(raw.data, eset.mas5) > plot(qc) Unfortunately the values are not correct ( at least I hope they're not). Is there somewhere I can find the correct values for these genes? Does Affymetrix has a repository of qcdf files? I looked everywhere in Netaffx, but couldn'r find anything? A few months ago, I found an unrelated repository, where someone uploaded some qcdf files, but now I can't find it anymore. Does someone has an idea as to where I can find something like that? Thanks for the help Assa [[alternative HTML version deleted]]
