Overview of the objective and dataset of the Microbiomics Challenge. Schematic description of the challenge (A). Participants were provided simulated metagenomics datasets representative of samples with increasing bacterial composition complexities and biases and including mouse host-read contamination. Real metagenomics datasets were generated from the sequencing of two independent libraries prepared from the commercially available ZymoBIOMICS DNA standard extracted from a known mixture of microorganisms, including eight bacterial species and two yeasts (B)
