EULER+Velvet-SC improves upon Velvet in all three plots. other. from publication: De Novo assembly of bacterial genomes from single cells | | ResearchGate. We discuss the theoretical aspects of various genome assemblers, identifying their working in EULER, EULER-SR and A-Bruijn graph assembly ter-. Pevzner PA, Tang H. Fragment assembly with double-barreled data. . The EULER-SR assembly package contains a suite of programs for correcting errors in. EULER-SR assembler replaces the higher measure tree optimization of the A- Bruijn graph by the maximum branching optimization on de Bruijn graphs.
