nm000110 NEMAR-native dataset

CHB-MIT

The CHB-MIT Scalp EEG Database is a collection of continuous EEG recordings from 24 pediatric subjects with intractable epilepsy, acquired at Children's Hospital Boston. The dataset comprises 686 EEG scans containing 198 annotated seizure events, recorded at 256 Hz using the International 10-20 electrode system with bipolar montages. Subjects (5 males and 18 females, ages 1.5-22 years) were monitored for several days following anti-seizure medication withdrawal to characterize seizure patterns and assess surgical intervention candidacy. The original EEG data in .edf format from PhysioNet has been converted to BIDS format with standardized channel naming and preserved non-EEG channels. Note: Surrogate dates were used to replace protected health information, which may result in inaccurate age calculations in automated reports.

Download this dataset

Pick a method. Large datasets skip the zip and use the streaming methods below — all resumable. Full download guide →

  1. Download archive (.zip) — 25.4 GB

    A single zip of the published version. Best for small/medium datasets.

    Download zip

  2. NEMAR CLI recommended

    Pulls the pinned version + annexed data and resumes cleanly. Install nemar-cli → 

    nemar dataset download nm000110
  3. DataLad

    Clone the dataset repo and fetch file content on demand. Docs → 

    datalad clone https://github.com/nemarDatasets/nm000110 nm000110
cd nm000110 && datalad get .
  4. git-annex

    Plain git + git-annex against the dataset repo. Docs → 

    git clone https://github.com/nemarDatasets/nm000110 nm000110
cd nm000110 && git annex get .
  5. Direct files (wget / curl / rclone)

    Every file with a stable, range-resumable URL from the manifest. Needs curl, jq, wget (or rclone/aria2c). Docs → 

    curl -s https://data.nemar.org/nm000110/v1.0.1/manifest.json | jq -r '.[].bytes_url' > urls.txt
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/nm000110), 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 nm000110
cd nm000110 && nemar dataset get
  3. Just the files.

    rclone, aria2c, or any HTTPS client works against data.nemar.org/nm000110/ — 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.
