mOTUs Table

The following table provides a description of each column in the mOTU collection:

Field Name	Type	Description
mOTU4	str	Unique identifier for the mOTU (compatible with versions 4.0 and 4.1).
Domain	str	Taxonomic domain assigned to the mOTU, derived from GTDB R226.
Phylum	str	Taxonomic phylum assigned to the mOTU, derived from GTDB R226.
Class	str	Taxonomic class assigned to the mOTU, derived from GTDB R226.
Order	str	Taxonomic order assigned to the mOTU, derived from GTDB R226.
Family	str	Taxonomic family assigned to the mOTU, derived from GTDB R226.
Genus	str	Taxonomic genus assigned to the mOTU, derived from GTDB R226.
Species	str	Taxonomic species assigned to the mOTU, derived from GTDB R226.
MicrobeAtlas	link	External link to the MicrobeAtlas database; returns a dash (-) if no mapping is available.
Representative	str	Identifier for the genome designated as the high-quality cluster representative for this mOTU.

Genome Table

The following table defines the metadata fields and quality metrics associated with the individual genomes (MAGs, SAGs, and isolates) in the collection.

Field Name	Data Type	Description
Genome	str	Unique identifier or name of the individual genome.
Domain	str	Taxonomic domain derived from GTDB R226.
Phylum	str	Taxonomic phylum derived from GTDB R226.
Class	str	Taxonomic class derived from GTDB R226.
Order	str	Taxonomic order derived from GTDB R226.
Family	str	Taxonomic family derived from GTDB R226.
Genus	str	Taxonomic genus derived from GTDB R226.
Species	str	Taxonomic species derived from GTDB R226.
mOTU4	str	The mOTU identifier (versions 4.0 and 4.1) to which this genome belongs.
Sample	str	The origin of the genomic data: the metagenomic sample for MAGs, or the source sample for Isolates/SAGs.
Study	str	The primary study or dataset from which the genome was recovered.
Q-Score	float	Integrated quality metric calculated as: \(Completeness - (5 \times Contamination)\).
Completeness	float	Estimated genome completeness percentage (0–100), determined by CheckM or Anvi’o.
Contamination	float	Estimated genomic contamination percentage (0–100), determined by CheckM or Anvi’o.
N50	int	Assembly quality metric; the length of the shortest scaffold such that 50% of the total assembly length is contained in scaffolds of this size or larger.
#Scaffolds	int	The total number of scaffolds in the genome assembly.
MAG	bool	Boolean flag; True if the genome is a Metagenome-Assembled Genome, False otherwise.
Is Rep	bool	Boolean flag; True if this specific genome is the designated representative for its mOTU cluster.
Representative	str	The name of the genome designated as the cluster representative for the associated mOTU.
