Release 56

The Ensembl project is pleased to announce release 56 of Ensembl (http://www.ensembl.org/). Highlights of this release are:

Reintroduction of our multi-species views. Alignments (image), formerly alignsliceview, shows pairwise or multiple alignments from the Ensembl Compara database, highlighting any gaps in the alignment.

Multi-species view, formerly known as multicontigview, displays pairwise alignments without gaps; multiple pairwise alignments can be configured to create a multiple alignment display. As well as genes, other types of features such as regulatory features can be displayed in this view, making this a very useful display for comparative genomic analysis.

A new tab has been added in release 56 based on a Regulatory Feature object. This will enable better display some of the data underlying the Ensembl regulatory build. The new pages are accessed from the gene displays by clicking on the 'Regulation' link in the left-hand menu and then clicking on a regulatory stable ID in either the image popup menus or the table.

From release 56, users can upload wiggle plot data in WIG and bedGraph formats and view this data on various location-based views. At the moment, only a single style, "wiggle", is available on Region in Detail, whereas a selection of density plots are available on whole chromosome and karyotype images. In addition, Region in Detail now supports greyscale rendering of BED scores via the useScore parameter in the file, and rendering of features in different colours via the itemRgb parameter and per-feature values.

New data in this release includes gene sets on two new species (Pig and Marmoset) and a new gene set on the existing Rat Rnor3.4 assembly. Also in this release is an updated human gene set which includes all the Havana manual annotation in the merge with the Ensembl automatic annotation set. This set represents the Encode project GENCODE 3b gene set. Also included is a new human variation database based on dbSNP 130 and mapped to assembly GRCh37.
