Quick Start

Download the core database tables and run your first query in two commands.

# 1. Download the database (~540 MB core tables)
atb fetch

# 2. Query
atb query --species "Escherichia coli" --hq-only --limit 10

If you don't have the parquet files yet:

# Download core tables from OSF (~540MB)
./bin/atb fetch

# Or download all tables including ENA metadata (~4.3 GB)
./bin/atb fetch --all

Core tables are ~540 MB

The default atb fetch downloads the core parquet tables (~540 MB), which is enough for most queries. For full ENA metadata or AMR tables, see Fetching & indexing data for all available options and how to select specific tables.
