Pearson correlation coefficient for read frequencies (within contigs) between sequencing sets. SS1-SS12 are sequencing sets from E.spp; SRR001658-SRR001661 are sequencing sets from E. grandis (Novaes et al., 2008). The colour scale indicates the strength of the correlation, from red (strongest correlations) to green (weakest correlations). All the correlation coefficients were significant, with a p-value <0.001.
