Hi, I would like to analyze some agilent aCGH copy number files. As a start, I would like to normalize this data. I don't know what is the standard way to do this. Which package is the standard one that people use for this purpose? The chips that I am looking at are the agilent sure print 1M (G4447a) array and a custom chip with similar format. My raw data is a text file with spot locations and intensities. It is a two color array.
