LORIS (Longitudinal Online Research and Imaging System) is a self-hosted web application that provides data- and project-management for neuroimaging research. LORIS makes it easy to manage large datasets including behavioural, clinical, neuroimaging and genetic data acquired over time or at different sites.

This Readme covers installation of LORIS@UVA using Docker.

Please consult the Loris documentation for more information. Other installation instructions and more LORIS documentation for developers can also be found on the LORIS ReadTheDocs website.

• Docker
• Docker Compose

Installing some dependencies may require sudo privileges. Other dependencies are defined through Dockerfiles. Consult the Loris repository for more information on these requirements.

1. Create environment file in the project repo to configure MySQL and CouchDB containers

   .env example

   MYSQL_DATABASE_NAME=$loris_db_name
   MYSQL_ROOT_PASSWORD=$db_root_password
   
   COUCHDB_USER=$dqt_user
   COUCHDB_PASSWORD=$couch_root_password

   $loris_db_name ⇾ "loris" or one-word project name

   ⚠️ Warning: Keep these passwords secret! Do not check the .env file into your repo!

2. Run docker compose build in the root Loris folder to build your Docker images

3. Run docker compose --env-file .env up -d in the root folder of the repository to start the service

   📝 Note: If you make any changes to the Dockerfile or docker-compose.yaml, you will need to rebuild the images using docker compose build before running docker compose up

4. Open your browser and go to: <loris-url>/installdb.php. This web page will prompt you for your mysql connection information. Follow the instructions to finalize LORIS installation, then restart Apache in the loris-web-1 Docker container (name could vary) using sudo service apache2 reload.

   📝 Note: <loris-url> is most likely localhost

   📝 Note: Use docker network inspect loris_default to find the IP Address for the MySQL database and use this for the Server Hostname

   📝 Note: Check the box for Use existing database and provide the database name from your mysql.env file

5. Follow the Setup Guide in the LORIS Wiki to complete your post-installation setup and configuration, and for more documentation.
