VALUE = generalized logarithm transformed values
Data were converted from .cel files and averaged across probes within each probeset using the Bioconductor package affy (version 1.22.1) within the statistical software system R (version 2.10.1), then transformed via a generalized logarithm transformation using the Bioconductor package LMGene (version 2.4.0).

A one-way analysis of variance (ANOVA) model was fitted to the data one probeset at a time. For probeset for which the global F test was significant at the 5% level, indicating significant differences between at least two levels of the factor, Tukey HSD post-hoc tests were conducted to test for significant differences among the comparisons of interest.
