Positive correlations between EBs and EAs in the two datasets from the ESTs and microarray. Three different definitions of EA were used to investigate the correlation between EAs and EBs in the two data sets from the microarray (left) and ESTs (right). Detailed definitions of the three different values on the y-axis are described in the main text. Kendall's tau values are indicated in the upper middle section in each box plot. All graphs consistently show that EA is positively correlated with EB at statistical significance (p < 0.01), although the size of tau varies with different tests.
