Illustration of the alignment of two reads by identifying a common k-mer in the overlap. The boxes labeled by K denote a common k-mer between the two reads. The symbol × denotes a sequencing error that would preclude a common k-mer from occurring in the immediate area. However, as long as the error rate is low enough and the overlap is sufficiently long, a common k-mer will exist with high probability.
