nm000140 NEMAR-native dataset

BNCI 2015-001 Motor Imagery dataset

A motor imagery EEG dataset comprising 12 healthy, right-handed naive subjects performing two-class imagery tasks (right hand palmar grip versus bilateral feet plantar extension) across two sessions. The dataset includes 13-channel EEG recordings at 512 Hz with preprocessed data (bandpass filtered 0.5-100 Hz, notch filtered at 50 Hz) and achieves 80% classification accuracy using LDA with common spatial patterns and logarithmic bandpower features, designed for brain-computer interface research and benchmarking.

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/nm000140), 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 nm000140
    cd nm000140 && nemar dataset get
  3. Just the files.

    rclone, aria2c, or any HTTPS client works against data.nemar.org/nm000140/ — 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.
