Dear BioCs, I'm receiving this error message: > MAp = normalizeWithinArrays(RG.mb) Error in switch(method, loess = { : printer layout information does not match M row dimension My printer informations are: > RG$printer $ngrid.r [1] 12 $ngrid.c [1] 4 $nspot.r [1] 23 $nspot.c [1] 24 attr(,"class") [1] "PrintLayout" I can normalize when I use the other methods, like median and loess. But I really need to perform the printtiploess normalization. Thanks, Priscila -- Priscila Grynberg, B.Sc., M.Sc.

Perhaps some of the probes are not in the data because they are normalization probes or for some other reason.

Just to complete my last email, my input file is a .csv file from scanarray express, but I'm using a generic source to read my maimages. Priscila [[alternative HTML version deleted]]
