colour         Colours a reference package's phylogeny based on taxonomic or phenotypic data
create         Create a reference package for a new gene, domain or orthologous group
evaluate       Evaluate the classification performance using clade exclusion analysis
layer          Layer extra annotation information on classifications with iTOL colours-style file(s)
package        Facilitate operations on reference packages
phylotu        Sort query sequences into clusters inferred from a reference package's phylogeny
purity         Characterize the sequences in a reference package using a curated database
train          Train a reference package's model used for correcting taxonomic rank classifications
update         Update an existing reference package with sequences found in a `classify` run
