Dear List, Several papers on analysis of microarrays mention saturation as a problem in some microarrays. I was wondering what standard practice was regarding detection of saturation (at what intensity level is a probe considered saturated). Once a probe is labeled as saturated, what is done about it? Any references would be appreciated, too. Thank you, Monnie Monnie McGee, Ph.D. Assistant Professor Department of Statistical Science Southern Methodist University Ph: 214-768-2462 Fax: 214-768-4035
