Hi everyone, I tried to read beadarry data in R with backgroundMethod="none". For some reason it still gives me the array's with a background correction. See below. Does this mean my "raw data" has allready been background corrected? I couldn't find it in the report. Thanks, Hajar BLData=readIllumina(arrayNames=array.namen,backgroundMethod="none",nor malizeMethod="Quantile",useImages=F) 'useImages=FALSE': please check that the 'singleChannel' argument is appropriate for your data set Found 24 arrays Reading raw data from ./5513091009_A_perBeadFile.txt Reading locally background corrected intensities [[alternative HTML version deleted]]
