nm000454 NEMAR-native dataset

A multimodal epilepsy dataset of paired 3-Tesla and 7-Tesla MRI and intracranial EEG (Penn 3T-7T, Pennsieve 662)

A multimodal dataset of paired 3-Tesla and 7-Tesla MRI (structural and resting-state fMRI) from 30 patients with drug-resistant focal epilepsy. For 15 of these patients it also provides curated ictal and interictal intracranial EEG epochs (ECoG and SEEG) with electrode localizations in MNI space. Preprocessing derivatives (fMRIPrep, FreeSurfer, iEEG-recon) are included. This is a BIDS redistribution of Pennsieve Discover dataset 662.

Download this dataset

dataset 213.8 GB exceeds 100.0 GB archive limit; use direct download. Choose a download method below; resume support depends on each file's storage type. Full download guide →

  1. NEMAR CLI recommended

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

    nemar dataset download nm000454
  2. DataLad

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

    datalad clone https://github.com/nemarDatasets/nm000454 nm000454
cd nm000454 && datalad get .
  3. git-annex

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

    git clone https://github.com/nemarDatasets/nm000454 nm000454
cd nm000454 && git annex get .
  4. 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/nm000454/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/nm000454), 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 nm000454
cd nm000454 && nemar dataset get
  3. Just the files.

    rclone, aria2c, or any HTTPS client works against data.nemar.org/nm000454/ — 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 nm000454 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 nm000454 --subjects sub-01,02 Also filters by --sessions, --tasks, --runs, --datatypes, --include and --exclude.
    A subset, step 1
    nemar dataset clone nm000454 Clones git-annex pointers only; fetches no file content. Creates ./nm000454.
    A subset, step 2
    cd nm000454 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/nm000454/v1.0.0/participants.tsv A direct HTTPS fetch works for any single file.
