Dear Sir, i am doing work on microarray data analysis in R using Bioconductor. i have installed all the default packages and other required packages. when i used "qc(myobject)" , i am getting the following error message: Error in setQCEnvironment(cdfn) : Could not find array definition file ' drosophila2cdf.qcdef '. Simpleaffy does not know the QC parameters for this array type. See the package vignette for details about how to specify QC parameters manually.

So, did you find more errors when you read the package vignette and specified the QC parameters manually, as the error message suggests? If so, please provide the code and the output of sessionInfo() so that folks can be maximally helpful. Sean [[alternative HTML version deleted]]
