Figure 2.

Box graph of correlation coefficients of the gene expression levels for 11,123 clones, comparing individual amplified samples to the gold standard of BC2 (idealizing unamplified poly(A)+ RNA). Each closed circle represents the correlation coefficient for each individual sample amplified with a particular protocol to the gold standard. The average and virtual correlation coefficients of the replicate samples for each protocol are shown below the graph.
