Class Method Details

.connect(species, release = Ensembl::ENSEMBL_RELEASE, args = {}) ⇒ Object

The Ensembl::Core::DBConnection#connect method makes the connection to the Ensembl core database for a given species. By default, it connects to release 50 for that species. You could use a lower number, but some parts of the API might not work, or worse: give the wrong results.

Examples:

# Connect to release 50 of human
Ensembl::Core::DBConnection.connect('homo_sapiens')

# Connect to release 42 of chicken
Ensembl::Core::DBConnection.connect('gallus_gallus')

Parameters:

• species (String) —

  Species to connect to. Must be in snake_case

• ensembl_release. (Integer) —

  Release to connect to (default = 60)
