Figure 6.

(A) Read yields (number of sequencing reads per hour) and their quality status during the first six hours of MinION shotgun metagenomic sequencing. The blue color indicates the count of 1D reads, the red and orange colors indicate the counts of 2D reads with either a mean Q-score of < or ≥9. (B) Read length distribution of 2D reads. Only the 2D reads within the length range of 0 to 1,200 bases were shown, including 96.6% of the total amount of 2D reads. The longest 2D read is 34,840 bases long, and the longest 2D read that passed the quality filter (mean Q-score ≥9) is 6,670 bases long.
