Figure 4

Number of errors at read position. Frequency of errors occurring at a specified read position (in relation to the coverage) in total (white) and without homopolymer association (gray). Bars are unstacked, homopolymer proportions plotted to the front. The boxplot below displays the quartiles of errors across read positions (total). Errors at the first positions are very infrequent, furthermore, this section of sequence is located outside the analyzed exon.
