Background:

DNA barcoding and meta-barcoding are essential for taxonomic identification.
Existing databases face challenges due to diverse markers and formatting needs.

Purpose of the Study:

To develop a flexible tool for creating custom DNA reference databases.
To support DNA barcoding and meta-barcoding applications across various taxa.

Main Methods:

A web and command-line interface was developed.
The tool allows on-the-fly database generation for any marker and taxonomic group.
Optional filtering, formatting, and restriction features are included.

Main Results:

The tool facilitates the creation of tailored reference databases.
Generated databases can be assigned DOIs for citation and sharing.
Supports both single-taxon identification and mixture analysis.

Conclusions:

This tool addresses the need for specialized reference databases in molecular biodiversity research.
It enhances the usability and reproducibility of DNA barcoding and meta-barcoding studies.
Promotes data sharing and citable resources in the field.
