Sequencing error rate correlation between different subsets of the data. Sequencing errors are ranked from lowest to highest along each axis. The color in each bin represents the number of positions having the corresponding error rates in the two subsets. (a-d) Phix174 data. (e-h) mtDNA data. Correlation coefficients are shown at the end of the title of each plot.
