Metalog
Metalog is a repository of manually curated metadata for metagenomics samples from diverse habitats across the globe. It provides consistently annotated sample metadata for human, animal, marine, and other environmental microbiome studies. The resource contains 80,423 human samples, including 66,527 gut microbiome samples, 10,744 animal samples, 5,547 ocean water samples, and 23,455 samples from other environmental habitats such as soil, sediment, and fresh water.
Key benefits
Manually curated metadata repository for metagenomics samples
Covers human, animal, marine, and environmental microbiome datasets
Provides consistent annotation of habitat-specific core features
Supports global exploration and comparison of metagenomics samples
Helps improve metadata quality and reuse in microbiome research
Applications
Discovery of metagenomics samples by habitat or metadata features
Comparative microbiome studies across humans, animals, and environments
Selection of datasets for reanalysis or meta-analysis
Exploration of disease status, medication, host species, captivity, salinity, and other variables
