Hello, I wonder if someone can explain to me how I can get the values that is generated in the .exp files using Affymetrix Microarray Analysis Suite ver 5.0 using Bioconductor. I tried to use affy lib and simpleaffy but the values I get is very different from that generated by the affymetrix MAS 5 software. I tried using MAS5 in bioconductor but again I get different values. thanks
