ONE installation and setup
ONE can be installed as a standalone package with python 3.7 or later by running,
pip install ONE-api
If you have installed the unified IBL environment, ONE will already have been automatically installed, so you can skip this step!
To start using ONE, we must first configure some settings that tell ONE whether it should connect to a database or use a local file system
Connect to IBL Public database
By default ONE is configured to connect to the public IBL database, this can be setup by typing the following
from one.api import ONE one = ONE(silent=True)
If you are having an issue at this stage, or need to re-configure ONE, please see this FAQ page.
Using local folder structure
ONE can also be used independently of a database by using a local cache directory. This can be setup in the following way
from one.api import One one = One(cache_dir='/home/user/downlaods/ONE/behavior_paper')
For more information about using ONE with a local cache directory please refer to this section.
Connecting to specific database (relevant for IBL users)
To connect to a specific database, for example the internal IBL Alyx database, a base-url argument must be given
from one.api import ONE one = ONE(base_url='https://alyx.internationalbrainlab.org')
When connecting to the IBL internal database you will be prompted to enter credentials. See the IBL Welcome Guide for more information.
The internal IBL database is only open to IBL members, please connect to our public database to access our publically available datasets
3. Post setup
Once you’ve setup the server you can initialise ONE in the following way and it will automatically connect to the default database configured in your settings,
from one.api import ONE one = ONE()
To change your default database, or re-run the setup for a given database, you can use the following
one = ONE().setup(base_url='https://test.alyx.internationalbrainlab.org', make_default=True)
To update, open a shell terminal, activate the environment
iblenv and launch the command:
pip install -U ONE-api
