Table 3 Alignment statistics for the 75× Escherichia coli dataset

From: Lighter: fast and memory-efficient sequencing error correction without counting

   Read level Base level
  k Mapped reads Increase (%) Matches/aligned base (%) Increase (%)
Original 3,464,137 99.038
Quake 19 3,373,498 −2.62 99.659 0.63
SOAPec 17 3,465,819 0.05 99.130 0.09

  1. k column shows k-mer size selected for each tool. First ‘Increase’ column shows percentage increase in reads aligned. Second ‘Increase’ column shows percentage increase in the fraction of aligned bases that match the reference genome. The original row is before error correction and the other rows are after error correction.
