Cogmood Backend

Backend for the NIMH MLC's CogMood experiments, adapted from the Niv lab tools for securely serving and storing data from online computational psychiatry experiments.

Documentation

For details on how to serve your experiment, how the code is organized, and how data is stored, please see the Documentation.

Running in docker for testing

1. cd to the cogmood_backend directory
2. Build the docker file:
   docker build -t cogmood_backend .
3. Run with directories bound:
   docker run --name running_backend -dp 5000:5000 -v $PWD/data:/cogmood_backend/data -v $PWD/metadata:/cogmood_backend/metadata cogmood_backend
4. Run tests:
   docker exec running_backend pytest

You can visit the site at 127.0.0.1:5000?PROLIFIC_PID=[some unused number]. If you install all the requirements in a conda environment or some such, you can also run pytest outside of docker.

Creating self signed certs for testing

Fill in the appropriate URL and IP in the following command to create self-signed certs for testing.

openssl req -trustout -x509 -newkey ec -pkeyopt ec_paramgen_curve:secp384r1 -days 3650 \
  -nodes -keyout cogmoodtest.key -out cogmoodtest.crt -subj "/CN={URL}" \
  -addext "subjectAltName=DNS:{URL},IP:{IP}"

You'll also need to create a dhparam file, which can take about 20 minutes: openssl dhparam -out /etc/nginx/cogmoodtest_dhparam.pem 4096
