Data were processed using the Microarray Suite 5 (MAS 5) protocol of Affymetrix. To simplify comparison between transforms, MAS 5 values of each array were log2 transformed and adjusted to an average of 8 units. In general, MAS 5 data do not perform as well as RMA or PDNN transforms.
+ +Data were processed using the Position-Dependent Nearest Neighbor (PDNN) method developed by Zhang and colleagues (2003. To simplify comparison between transforms, PDNN values of each array were adjusted to an average of 8 units and a variance of 2 units. This data set was run as a single large batch with careful consideration to balancing samples by sex, age, and environment.
+ +Data were processed using the RMA protocol and are presented with secondary normalization to an average expression value of 8 units. To simplify comparison between transforms, RMA values of each array were adjusted to an average of 8 units and a variance of 2 units. This data set was run as a single large batch with effort to balance samples by sex, age, and environment.
