nm000446 NEMAR-native dataset

STN local field potentials from awake Parkinson's disease patients ON and OFF medication, with and without DBS (Wiest et al. 2023)

Subthalamic nucleus (STN) local field potentials recorded together with scalp EEG and accelerometry from patients with Parkinson's disease 3-6 days after DBS surgery, while the leads were externalised. Recordings were made OFF and ON dopaminergic medication, at rest and during sessions with and without 130 Hz STN deep brain stimulation. The data underlie an analysis showing that the aperiodic exponent of STN field potentials increases with levodopa and with DBS, and are provided in BIDS format with BrainVision files converted from Spike2 exports.

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) — 24.4 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 nm000446
  3. DataLad

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

    datalad clone https://github.com/nemarDatasets/nm000446 nm000446
    cd nm000446 && datalad get .
  4. git-annex

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

    git clone https://github.com/nemarDatasets/nm000446 nm000446
    cd nm000446 && 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/nm000446/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/nm000446), 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 nm000446
    cd nm000446 && nemar dataset get
  3. Just the files.

    rclone, aria2c, or any HTTPS client works against data.nemar.org/nm000446/ — 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 nm000446 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 nm000446 --subjects sub-01,02 Also filters by --sessions, --tasks, --runs, --datatypes, --include and --exclude.
    A subset, step 1
    nemar dataset clone nm000446 Clones git-annex pointers only; fetches no file content. Creates ./nm000446.
    A subset, step 2
    cd nm000446 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/nm000446/v1.0.0/participants.tsv A direct HTTPS fetch works for any single file.
