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/on004022), 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 on004022
cd on004022 && nemar dataset get
  3. Just the files.

    rclone, aria2c, or any HTTPS client works against data.nemar.org/on004022/ — 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.

NEMAR-curated copy of OpenNeuro ds004022

This is the NEMAR-curated copy. We pull from OpenNeuro periodically; each pull is a major version bump (vN.0.0). Versions between pulls (vN.x.y) are NEMAR-side fixes and improvements.

This dataset consists of raw 18-channel EEG and functional near infrareds(fNIRS) from 7 human paticipants with orthopedic Impairment during motor imagery(MI). The participants performed a series of MI-related trials across three sessions. These sessions comprised 40 trials, of which four different MI tasks were presented in random order (e.g., Reach → Twist → Lift → Reach → Grasp → Grasp → Twist → Reach → Lift → Reach). Each trial began with 3 s of fixation cross. The monitor then displayed a 4 s visual cue, followed by 3 s of letters indicating the ready state with a gray screen to eliminate the afterimage. The participants were then instructed to perform the imaginary movement for 5 s in the given order.
