Finding information about species and genomes in Ensembl, Demo

The front page of Ensembl is found at ensembl.org. It contains lots of information and links to help you navigate Ensembl:

At the top left you can see the current release number and what has come out in this release. To access old releases, scroll to the bottom of the page and click on View in archive site.

Click on the links to go to the archives. Alternatively, you can jump quickly to the correct release by putting it into the URL, for example e98.ensembl.org jumps to release 98.

Click on View full list of all species.

Click on the common name of your species of interest to go to the species homepage. We’ll click on Human.

Here you can see links to example pages and to download flatfiles. To find out more about the genome assembly and genebuild, click on More information and statistics.

Here you’ll find a detailed description of how to the genome was produced and links to the original source. You will also see details of how the genes were annotated.

The current genome assembly for human is GRCh38. If you want to see the previous assembly, GRCh37, visit our dedicated site grch37.ensembl.org.

Let’s take a look at the Ensembl Genomes homepage at ensemblgenomes.org.

Click on the different taxa to see their homepages. Each one is colour-coded.

You can navigate most of the taxa in the same way as you would with Ensembl, but Ensembl Bacteria has a large number of genomes, so needs slightly different methods. Let’s look at it in more detail.

There’s no full species list for bacteria as it would be hard to navigate with the number of species. To find a species, start to type the species name into the species search box. A drop down list will appear with possible species.

For example, to find a sub-strain of Clostridioides difficile start typing in the species name. Due to the autocomplete, you’ll see useful results as soon as you get to clostridio.

The drop down contains various strains of Clostridioides difficile. Let’s choose Clostridioides difficile 630. This will take us to another species homepage, where we can explore various features.

Unlike the human homepage, there is no prose description of the genome or gene annotation, as these pages were generated automatically.

Our newest genomes, such as those coming from the Darwin Tree of Life, are available rapid.ensembl.org with limited annotation.
