Examining Perceptual Grouping on Stages of Processing in Visual Working Memory: An ERP Study

This EEG dataset comprises electrophysiological recordings from 53 subjects performing a bilateral change-detection task designed to investigate how perceptual grouping based on color repetition influences visual working memory (VWM) processing. Using event-related potentials (ERPs), the study temporally isolates neural correlates of distinct VWM stages—individuation encoding, maintenance, initial comparison, percept-memory comparison, and decision making—through specific ERP markers (N2pc, CDA, N2, FN400). The dataset includes 1,248 trials recorded at 512 Hz from a 71-channel BioSemi ActiveTwo system and is structured according to BIDS standards.

Download this dataset

dataset 269.1 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 on006979
  2. DataLad

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

    datalad clone https://github.com/nemarDatasets/on006979 on006979
cd on006979 && datalad get .
  3. git-annex

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

    git clone https://github.com/nemarDatasets/on006979 on006979
cd on006979 && 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/on006979/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/on006979), 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 on006979
cd on006979 && nemar dataset get
  3. Just the files.

    rclone, aria2c, or any HTTPS client works against data.nemar.org/on006979/ — 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.
