WebSep 5, 2024 · In general, our pipeline can generate accurate assemblies with fewer than 1000 reads, regardless of quality; but if we focus on high-quality reads, we can begin to detect contamination. We find that only a small fraction of high-quality reads fails to map to an assembly, while increased levels of non-mapping reads correlate with contamination. WebApr 5, 2024 · The ‘greater than 10 kb’ filter for raw ONT reads resulted in a higher-quality assembly than the ‘greater than 8 kb’ and ‘greater than 5 Kb’ filters.
