Clustering benchmarks on two datasets from a high-CO₂ cold-water geyser. The number of clusters with different completeness levels are shown at two contamination levels. All programs were run with their default parameters. DASTool was run with two combinations: (1) DASTool_MM for MetaDecoder and MetaBAT2; (2) DASTool_CM for CONCOCT and MetaBAT2. MetaDecoder with minimum sequence length setting to 1 Kb (MetaDecoder1000) was also added for benchmarking
