Download pre-built indexes
Pre-built indexes for all reference databases are available for download. Each compressed archive contains the Kaiju .fmi index file, as well as the corresponding nodes.dmp and names.dmp from the NCBI taxonomy.
See the Quickstart guide for instructions on installing Kaiju and running it with a downloadable index. The README contains more detailed information about the program and the databases.
Files are hosted on Amazon AWS S3 storage through the Open Data Sponsorship Program.
