Long-read reconstruction of many diverse haplotypes with devider.

ABSTRACT: Reconstructing exact haplotypes is important when sequencing a mixture of similar sequences. Long-read sequencing can connect distant alleles to disentangle similar haplotypes, but handling sequencing errors requires specialized techniques. Here, we present devider, an algorithm for haplotyping small sequences, such as viruses or genes, from long-read sequencing. devider uses a positional de Bruijn graph with sequence-to-graph alignment on an alphabet of informative alleles to provide a fast assembly-inspired approach compatible with various long-read sequencing technologies. On a synthetic Oxford Nanopore Technologies (ONT) long-read data set containing seven HIV strains, devider recovers 97% of the haplotype content and has the most accurate abundance estimates while taking <4 min
