Hi, I am the mantainer of oneChannelGUI. My library is an extension of the functions available in affylmGUI. Today a was doing some testing and I realized the presence of an error when I was loading conventional 3'IVT Affymetrix arrays. During the loading of .CEL files and error occured: Error in colnames(RawAffyData at exprs) : error in evaluating the argument 'x' in selecting a method for function 'colnames' This error is present in line 3062 of main.R of affylmGUI, in function OpenCDFandTargetsfiles(). The error is removed if I modify the line to: Try(SlideNamesVec <- colnames(exprs(RawAffyData))) Cheers Raffaele
