MEG: Major Depression & Probabilistic Learning Task

This dataset comprises magnetoencephalography (MEG) recordings from participants with major depressive disorder (MDD, n=52) and non-depressed controls (CTL, n=38) collected during a probabilistic selection reinforcement learning task. The study investigates the Reward Positivity ERP/MEG component and ventromedial frontal cortex activity associated with reward processing in depression. Diagnostic group assignment was determined via SCID interview.

wget -xc -i urls.txt

Compute on this dataset

Two routes today, with a third (in-browser one-click submission) landing soon.

  1. NeuroScience Gateway (NSG) portal.

    NSG runs EEGLAB / Brainstorm / MNE pipelines on supercomputing time donated by SDSC. Create an account, point a job at this dataset's S3 prefix (s3://nemar/on005356), and submit.
    nsgportal.org →

  2. Local processing with nemar-cli.

    Pull the dataset to your machine and run any toolbox locally. Honors the published version pinning. 

    npm install -g nemar-cli
nemar dataset clone on005356
cd on005356 && nemar dataset get
  3. Just the files.

    rclone, aria2c, or any HTTPS client works against data.nemar.org/on005356/ — the manifest carries presigned S3 URLs.

Direct compute access is coming soon. One-click NSG submission from this page is scoped for a follow-up phase. Tracked on nemarOrg/website#6.
