Full-length de novo viral quasispecies assembly through variation graph construction

Motivation Viruses populate their hosts as a viral quasispecies: a collection of genetically related mutant strains. Viral quasispecies assembly is the reconstruction of strain-specific haplotypes from read data, and predicting their relative abundances within the mix of strains is an important step for various treatment-related reasons. Reference genome independent (‘de novo’) approaches have yielded benefits over reference-guided approaches,...
