This package is a toolkit for working with Biological Observation Matrix (BIOM) files. Features include reading/writing all ‘BIOM’ formats, rarefaction, alpha diversity, beta diversity (including ‘UniFrac’), summarizing counts by taxonomic level, subsetting, visualizations, and statistical analysis. All CPU intensive operations are written in C.
