Cross-Environment Multi-Paradigm Motor Imagery EEG Dataset

This dataset comprises EEG recordings from 84 healthy participants performing motor imagery tasks across multiple controlled environments (laboratory and simulated hospital), with a supplementary cohort of 3 participants recorded in microgravity conditions in a space station environment. The dataset includes multiple motor imagery paradigms (Graz, SSMVEP-MI, and hybrid variants) with 64-channel EEG recordings at 1000 Hz sampling rate (69 channels acquired, 60 channels used in analysis), designed to investigate environmental effects on brain-computer interface performance and enable cross-environment robustness evaluation. This dataset is a republication of OpenNeuro ds007221 on the NEMAR platform to enhance accessibility and discoverability within the neuroimaging research community.

Download this dataset

dataset 143.6 GB exceeds 100.0 GB archive limit; use direct download. Use one of the streaming methods below — all resumable. Full download guide →

  1. NEMAR CLI recommended

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

    nemar dataset download on007221
  2. DataLad

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

    datalad clone https://github.com/nemarDatasets/on007221 on007221
cd on007221 && datalad get .
  3. git-annex

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

    git clone https://github.com/nemarDatasets/on007221 on007221
cd on007221 && git annex get .
  4. 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/on007221/v1.0.0/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/on007221), 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 on007221
cd on007221 && nemar dataset get
  3. Just the files.

    rclone, aria2c, or any HTTPS client works against data.nemar.org/on007221/ — 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.
