What's New in Release 22

Did you know...?

You can look up your variants against Ensembl Genomes by using the Variant Effect Predictor (VEP), now with a new web interface.

Mapping between assembly and gene set versions

Assembly converter diagram

Ensembl Metazoa aims to reflect the latest INSDC assembly for each species, which sometimes means that an older version is replaced, as is the case for Bombyx mori in release 22. Prior to release 22, the assembly was the one used by SilkDB, but the latest release exactly reflects the INSDC record. (Full details of the Bombyx mori assembly in Ensembl Metazoa.)

We provide bi-directional mappings between assembly versions, which can be accessed through the Perl API, or the REST service. In addition, an Assembly converter tool in the web interface performs "liftover" of features from one version of an assembly to another.

Release 22 of Ensembl Metazoa includes several gene set updates, including those of Daphnia pulex and Nematostella vectensis. For these two species we have switched to use the genes from ENA, rather than the JGI genes; the ENA genes are a filtered subset of the JGI set, and trancripts have cross-references back to the JGI records. The new gene set uses different stable IDs to previous Ensembl Metazoa releases, and there are two ways to map these between versions. The ID History section of a Gene or Transcript page (e.g. Daphnia pulex PGI) shows former stable IDs. And the ID History converter tool maps between lists of old IDs and new IDs.
