Figure Lengend Snippet: CLAE enables efficient error correction with or without a reference. A) Overview of CLAE's error correction workflow. B) Comparing base‐calling modes for R9 and R10 flow cells. Consensus accuracy (y‐axis) versus subread count (x‐axis) across base‐calling modes (‐ i ‐). Number of ≥Q30 HF reads (arrows) depends on base‐caller and flow cell (‐ ii ‐). Both reference‐based and non‐reference modes effectively reduce substitution, deletion, and insertion errors (‐ iii ‐). C) Alignment fractions of the shorter read (AF) for HF and raw (non‐HF) reads, shown for Lambda phage DNA (left) and E. coli genomic DNA (right). HF were generated with the reference mode (ref). Dotted triangles denote reads with <90% AF. D) Error correction efficiencies using “plus (red)” strands only, “minus (green)” strands only, and both “plus and minus” (blue) strands (‐ i ‐). Many errors occur at error‐prone k‐mers (‐ ii ‐). Using both strands reduces the subread threshold to achieve ≥ Q30 HF reads (‐ iii ‐).
Article Snippet: Genomic DNA from E. coli strain K12 (NEB C2987PVIAL) was extracted using QIAGEN Genomic‐tip 500/G (10 262) & Genomic DNA Buffer Set (19 060) according to the manufacturer's protocol.
