Magnetoencephalographic (MEG) Pitch and Duration Mismatch Negativity (MMN) in First-Episode Psychosis

This magnetoencephalographic (MEG) dataset comprises auditory oddball paradigm recordings from participants with first-episode psychosis and healthy controls, designed to investigate mismatch negativity (MMN) responses to pitch and duration deviants. The study includes three participant groups: healthy controls, first-episode schizophrenia, and first-episode affective psychosis patients. Data were collected as part of the Pittsburgh Early Psychosis Program between December 2017 and September 2021. The dataset includes clinical, neuropsychological, demographic, and medication data in the derivatives.

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/on004837), 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 on004837
cd on004837 && nemar dataset get
  3. Just the files.

    rclone, aria2c, or any HTTPS client works against data.nemar.org/on004837/ — 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.
