Hi All,

I've got an Affymetrix dataset which I need to process and finally get the
list of genes and their respective expression levels. Without having much
prior idea and experience, I tried the ReadAffy() function within the
directory containing the .CEL files and I came across the error saying :

Error in read.affybatch(filenames = l$filenames, phenoData = l$phenoData,  :

  Cel file MN.CEL does not seem to have the correct dimensions

Then I tried the following command for each individual .CEL files of that
investigation (as I am not sure how to get such information about all the
files using a single command):

whatcdf ("filename", compress = getOption("BioC")$affy$compress.cel)

I could see that the investigation is referring to different CDF files.

Could you please inform me how I should proceed !
