nm000434 NEMAR-native dataset

SenseFOG: subthalamic LFP (Medtronic Percept), EEG/EMG and IMU kinematics during sitting, standing, walking, stopping and freezing of gait in Parkinson's disease

This dataset contains multimodal recordings from 12 patients with idiopathic Parkinson's disease who have bilateral subthalamic deep brain stimulation (Medtronic Percept PC). Recordings were made after overnight withdrawal of dopaminergic medication with stimulation OFF, during sitting, standing, walking through a narrow corridor, walking with self-initiated stops, and walking with a dual task. Signals include bipolar subthalamic local field potentials, 48-channel scalp EEG with surface EMG, and inertial sensor kinematics, supporting study of freezing of gait.

Download this dataset

Pick a method. Large datasets skip the zip; resume support depends on each file's storage type. Full download guide →

  1. Download archive (.zip) — 3.4 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 nm000434
  3. DataLad

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

    datalad clone https://github.com/nemarDatasets/nm000434 nm000434
cd nm000434 && datalad get .
  4. git-annex

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

    git clone https://github.com/nemarDatasets/nm000434 nm000434
cd nm000434 && git annex get .
  5. Direct files (wget / curl / rclone)

    Every file is listed by its stable manifest URL. Single-range requests and resume are currently supported for annex-backed entries; git-tracked files are served as full bodies. Real chunk-only byte delivery still awaits isolated, non-synthetic acceptance. Needs curl, jq, wget (or rclone/aria2c). Docs → 

    curl -s https://data.nemar.org/nm000434/v1.0.0/manifest.json | jq -r '.[].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/nm000434), 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 nm000434
cd nm000434 && nemar dataset get
  3. Just the files.

    rclone, aria2c, or any HTTPS client works against data.nemar.org/nm000434/ — the manifest carries stable data-plane file URLs. Single-range requests are supported for annex-backed entries; git-tracked files are served as full bodies. Real chunk-only byte delivery remains under isolated acceptance.

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.

    How to download

    The dataset
    nemar dataset download nm000434 Clones and fetches in one step. Content under stimuli/ and derivatives/ is skipped by default because those trees can be large; add --stimuli --derivatives for the whole thing.
    A subset, one step
    nemar dataset download nm000434 --subjects sub-01,02 Also filters by --sessions, --tasks, --runs, --datatypes, --include and --exclude.
    A subset, step 1
    nemar dataset clone nm000434 Clones git-annex pointers only; fetches no file content. Creates ./nm000434.
    A subset, step 2
    cd nm000434 The get command below reads the clone's annex, so it only works from inside the clone.
    A subset, step 3
    nemar dataset get <files> Pulls the files you actually need. Skips stimuli/ and derivatives/ unless the path you ask for is under one of them.
    One small file
    https://data.nemar.org/nm000434/v1.0.0/participants.tsv A direct HTTPS fetch works for any single file.
