An example of binning reads from four species in the genus of
α and λ represents the estimated relative species abundance and k-mer coverage, respectively. The real genome sizes, α and λ are listed in the parentheses of the last table in the figure. After updating k-mer occurrences for k-mers occurring fewer than 4 times, the estimated α becomes more accurate. After removing small groups, the estimated species number and α become more accurate.
