Data processing The MAS5.0 Normalization is performed using the justMAS function in the simpleaffy package of Bioconductor ( The target value is 500 for all cases. The code was developed using R2.4.1, Bioconductor 1.9, and simpleaffy 2.8.0. The CDF files were downloaded from the Bioconductor website at The normalization scripts are available from the PLEXdb team by request.
