Fig. 4From: Improving the sensitivity of long read overlap detection using grouped short k-mer matchesTwo cases contributed to the identical characters at an aligned position in the overlapping region of S1 and S2. S1 and S2 are two reads sequenced from the same region of the underlying genome and form an overlap. Top: both bases on S1 and S2 are correct, forming a match. Bottom: both bases on S1 and S2 are sequencing errors, and substituted by the same characterBack to article page
