The number of identified genomes are shown at two different precision levels, ≥95% (A, C and D) or ≥90% (B, D and F). The number of identified genomes recovered with a completeness (recall) level 90%, 80%, 70%, 60%, or 50% are represented by different shades of gray, with 90% being the darkest. Benchmarking results using the high complex dataset (A and B), medium complex dataset (C and D), and low complex dataset (E and F) are shown. All the tools (MyCC, CONCOCT, COCACOLA, BinSanity, MaxBin 2 and MetaBAT 2) were run using their default parameters. Completeness and precision were calculated with the ground truth of each dataset.
