nm000165 NEMAR-native dataset

MUniverse Grison et al 2025

High-density surface electromyography (HDsEMG) recordings from the tibialis anterior muscle of one healthy subject during submaximal isometric ankle dorsiflexions at force levels ranging from 10 to 70 percent maximum voluntary contraction. The dataset comprises 128-channel recordings from two electrode arrays and includes labeled motor unit spike trains derived from concurrent invasive EMG recordings. This dataset supports investigation of motor unit recruitment and control strategies during graded voluntary contractions.

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/nm000165), 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 nm000165
cd nm000165 && nemar dataset get
  3. Just the files.

    rclone, aria2c, or any HTTPS client works against data.nemar.org/nm000165/ — 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.
