**What it does**

GTDB-Tk is a software toolkit for assigning objective taxonomic classifications to bacterial and archaeal genomes
based on the Genome Database Taxonomy GTDB. It is designed to work with recent advances that allow hundreds or
thousands of metagenome-assembled genomes (MAGs) to be obtained directly from environmental samples. It can also
be applied to isolate and single-cell genomes. 

This tool accepts one or more fasta (genome) files and determines taxonomic classification of genomes by
maximum-likelihood (ML) placement.  The classification workflow consists of three steps: identify, align, and
classify.

The identify step calls genes using Prodigal, and uses HMM models and the HMMER package to identify the 120 bacterial
and 122 archaeal marker genes used for phylogenetic inference.  Multiple sequence alignments (MSA) are obtained by
aligning marker genes to their respective HMM model.

The align step concatenates the aligned marker genes and filters the concatenated MSA to approximately 5,000
amino acids.

Finally, the classify step uses pplacer to find the maximum-likelihood placement of each genome in the GTDB-Tk
reference tree. GTDB-Tk classifies each genome based on its placement in the reference tree, its relative evolutionary
divergence, and/or average nucleotide identity (ANI) to reference genomes.

Results can be impacted by a lack of marker genes or contamination.
