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.

'Powered by Ensembl' logo


Ensembl are active collaborators in a number of projects, contributing code, know-how and a platform from which to distribute data.

Project Description Code used/data provided
1000 Genomes A web browser and ftp sites are provided to access human genetic variation catalogued by the project. Web front-end derived from Ensembl webcode
Avianbase Sequence and annotation of 44 bird species in an Ensembl framework. Web front-end derived from Ensembl webcode
Blueprint Epigenomics project analysing samples from healthy and diseased individuals. Track Hub available on the Ensembl browser
Ensembl Genomes Websites presenting annotation for bacteria, protists, fungi, plants and invertebrate metazoa Web front-end derived from Ensembl webcode, Ensembl schema databases, Ensembl pipelines and Perl API
gEVAL This browser can be used to inspect the reference assemblies of human, mouse and zebrafish being created by the GRC Customised webcode, pipelines (not genebuild) and compara
HEROIC Functional genomics data for Mouse (Mus musculus) Data viewable on Ensembl via DAS.
Neanderthal Genome Browser Preliminary assembly of Homo sapiens neanderthalensis. Web front-end derived from Ensembl webcode, Ensembl schema databases.
WormBase Parasite Website presenting draft genome sequences for helminths (parasitic nematodes and flatworms) Web front-end derived from Ensembl webcode, Ensembl schema databases, Ensembl Compara, REST API and (slightly modified) BioMart
NextGen A collaborative project investigating biodiversity of livestock species. Variant call sets produced using the Ensembl VEP, viewable in the Ensembl browser.
Quantomics Large-scale project to analyse sequence and variation in livestock genomes. Sequence alignments created using the Ensembl Compara pipelines.

External projects

Our open access data and open source code mean that many projects are able to make use of Ensembl data and software without our active involvement. We're happy to list those we know about here, but if your project is e!mpowered and you're not on this list, let us know.

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.


An open source Java API (JEnsembl) has been developed by the Bioinformatics Group at The Roslin Institute. The code has been designed to be version-aware (a single installation works against current and previous releases) and is hosted, together with documentation, examples and contact information for the Roslin group, at SourceForge.

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