(a) Pearson correlation coefficients among normalized mapped read counts (see Methods for details) for three preterm, three term individuals and a pooled term sample. Term samples are visibly correlated amongst each other, whereas higher heterogeneity amongst the preterm population is expected given their differing treatment regimens and developmental stages. A similar correlation heatmap using Spearman correlation coefficients is shown in Supplementary Figure 6 for completeness. (b) A four-way Venn diagram shows the number of expressed genes (>10 FPKM) among three individual term samples and a sequenced pooled sample. In the center of the diagram, 2132 genes are expressed in the pooled sample and all three individuals at greater than 10 FPKM. This large number of shared genes indicates that the sequencing procedure is consistent across sets of samples.
