Projects using Ensembl

The Ensembl project is both a source of genome sequence related data ( and an open source software system that can be used to organise any such data.

User-contributed code

Whilst we have developed a comprehensive Perl API in-house, we welcome contributions in other programming languages from the community.


A Ruby API has been developed by Jan Aerts. A small example, showing what it can do (including coordinate transformation and reflecting on the types of associations for a given class) can be found on the wiki page.

Note that we do not support these user-contributed packages - please contact the original developer if you have any questions or comments.

Ensembl-powered Websites

Some projects make use of the Ensembl software system, or are derived from it.
