### Kaiju custom database

To build a kaiju database, you need three components: a FASTA file with the protein sequences, the NCBI taxonomy dump files, and you need to define the uppercase characters of the standard 20 amino acids you wish to include.
A number of kaiju pre-built indexes for reference datasets are maintained by the the developers of kaiju and made available on the [kaiju website](https://bioinformatics-centre.github.io/kaiju/downloads.html). These databases can directly be used to run the workflow with Kaiju.

In case the databases above do not contain your desired libraries, you can build a custom kaiju database. To build a kaiju database, you need three components: a FASTA file with the protein sequences, the NCBI taxonomy dump files, and you need to define the uppercase characters of the standard 20 amino acids you wish to include.

:::warning
The headers of the protein fasta file must be numeric NCBI taxon identifiers of the protein sequences.
