ENA captures, preserves and presents the world's nucleotide sequence data. New content is included in ENA on a continuous basis and are distributed daily from our browser and RESTful service. The ENA assembled/annotated sequence release provides a quarterly snapshot of content in this important subset of ENA.


Please note that from release 141 we will stop including cross referencing (XREF) information being inserted into the released flat files.  Due to the periodic release cycle and limitations of the format, the XREF lines contained in flat files could not be up to date. Up to date XREF information can only be available from the XREF API ( and against records in the web browser, with further enhancements to this service with the release of the new ENA browser later this year. These services are updated on a daily basis and will contain the latest XREF information.
