Most arrays were highly correlated within the prefrontal cortex (PFC) and hippocampus (HPC). Quantile normalized arrays were compared by pairwise Pearson correlation and clustered according to inter-sample correlation values. (A) In the PFC, most arrays were highly correlated, with correlation values >0.94. Two samples were identified as outliers, due to their separate clustering and apparent discordance with other arrays. (B) In the HPC, arrays were highly correlated, with correlation values >0.92, and no samples clustered individually. Samples in either tissue did not cluster by termination day (Day), adjuvant exposure (Adjuvant), prenatal treatment (Treatment), or sample type (Type).
