Sub-sampling. Sensitivity (left y axis) and run-time (right y axis) at species level for one randomly selected CAMI high complexity sample. Each sub-sample was executed five times. Linesrepresent the mean and the area around it the maximum and minimum achieved values. Run-time stands for the time to execute the MetaMeta pipeline. The evaluated sample sizes are 100, 50, 25, 16.6, 10, 5, and 1%. 16.6% is the exact division among six tools, using the the whole sample. Sub-samples above that value were taken with replacement and below without replacement. The plot is limited to a value of 0.57 (left y axis) that is the maximum possible sensitivity value that could be achieved with the given tools and databases
