Getting Started with MiGA

Welcome to the Microbial Genomes Atlas Online


Query the NCBI Genome database (Prokaryotes) with your own genomes to determine the most likely taxonomic classification and novelty rank.


Query the collection of reference genomes in the NCBI RefSeq database with your own genomes to identify the closest high-quality genomes available.


Submit your data to this project if you want to preprocess your genomic or metagenomic dataset without additional fine-resolution taxonomic analyses.

Upload genome or metagenome


If you want high resolution within well characterized species, query select clade-specific databases for typing using Average Nucleotide Identity (ANI).

List clade projects


We're currently expanding MiGA to include environment-specific collections of genomes. If you would like to see an additional set included, please contact us.
