In line with EMBL-EBI policy, from the end of 2015 Ensembl will be removing support for DAS from our browser. This means that we will no longer provide our annotations over DAS and that we will not visualise third party annotation provided to us via DAS. If you have data with genomic coordinates that you wish to present in Ensembl then we recommend that you do this using TrackHubs. For annotation on other coordinate systems, we are currently working on providing support for this and will announce developments in this area over the course of the coming year. If you need more details then please get in touch with us at email@example.com.
