The microbial association mapping of body mass index (BMI) in American Gut Project subjects (FDR = 0.10). The associated species with corresponding significant taxonomic groups identified by OMiAT-HBH and OMiAT-SST are highlighted in the taxonomic tree. Among six detected species, [Eubacterium] biforme in phylum Firmicutes is also detected by the traditional BH method. The taxonomic tree was generated using GraPhlAn [46]. The nodes on the tree from inner to outer circles are the phylum, class, order, family, genus, and species rank. The corresponding annotations are written in the reverse order. Family rank is selected to conduct the screening test for massMap
