hi at all. I need to perform the analysis of a dataset of nine .cel files, chipset hgu133a affymetrix. I've downloaded and installed R 1.7.0 and Bioconductor 1.1 and hgu133a1.2.1 packages for windows (pc athlon1.4Gb, 512Mb ram under win2000pro OS). After I've started R and gived my working dir., I load affy and hgu133a, but when I type: mydata <- ReadAffy() the answer is: Warning messages: 1: the condition has length > 1 and only the first element will be used in: if (dim(intensity(cel)) != dim.intensity) stop(paste("CEL file dimension mismatch !\n(file", 2: the condition has length > 1 and only the first element will be used in: if (dim(intensity(cel)) != dim.intensity) stop(paste("CEL file dimension mismatch !\n(file", 3: the condition has length > 1 and only the first element will be used in: if (dim(intensity(cel)) != dim.intensity) stop(paste("CEL file dimension mismatch !\n(file", 4: the condition has length > 1 and only the first element will be used in: if (dim(intensity(cel)) != dim.intensity) stop(paste("CEL file dimension mismatch !\n(file", 5: the condition has length > 1 and only the first element will be used in: if (dim(intensity(cel)) != dim.intensity) stop(paste("CEL file dimension mismatch !\n(file", 6: the condition has length > 1 and only the first element will be used in: if (dim(intensity(cel)) != dim.intensity) stop(paste("CEL file dimension mismatch !\n(file", 7: the condition has length > 1 and only the first element will be used in: if (dim(intensity(cel)) != dim.intensity) stop(paste("CEL file dimension mismatch !\n(file", 8: the condition has length > 1 and only the first element will be used in: if (dim(intensity(cel)) != dim.intensity) stop(paste("CEL file dimension mismatch !\n(file", 9: the condition has length > 1 and only the first element will be used in: if (dim(intensity(cel)) != dim.intensity) stop(paste("CEL file dimension mismatch !\n(file", what is the problem? Can you help me, please?

in short: move to affy-devel with R-1.7.0 L.
