We describe the method BLASR (Basic Local Alignment with Successive Refinement) for mapping Single Molecule Sequencing (SMS) reads that are thousands to tens of thousands of bases long with divergence between the read and genome dominated by insertion and deletion error. We also present a combinatorial model of sequencing error that motivates why our approach is effective. The results indicate that mapping SMS reads is both highly specific and rapid.
