nm000131 NEMAR-native dataset

Wang2021 – Combined SSVEP dataset with single stimulus location for two inputs

A derivative EEG dataset implementing a combined steady-state visual evoked potential (SSVEP) brain-computer interface paradigm with spatially overlapping stimuli presented at a single location. The dataset comprises 8 healthy subjects performing a covert attention task to discriminate four arrow directions (up, down, left, right) flickering at distinct frequencies (7.73–14.17 Hz) derived from an 85 Hz CRT refresh rate. EEG signals were recorded at 1000 Hz using a 32-channel ANT Neuro system across two experimental schemes examining different attentional mechanisms.

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/nm000131), 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 nm000131
cd nm000131 && nemar dataset get
  3. Just the files.

    rclone, aria2c, or any HTTPS client works against data.nemar.org/nm000131/ — 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.
