nm000133 NEMAR-native dataset

Alljoined1

Alljoined1 is a 64-channel EEG dataset comprising neural responses from eight healthy adults (6 male, 2 female; mean age 22 ± 0.64 years) viewing 10,000 natural images each during rapid serial visual presentation (RSVP) with an oddball detection task. The dataset contains approximately 46,080 epochs across 13 sessions, with stimuli drawn from the Natural Scenes Dataset and MS-COCO. Raw data are preserved in 24-bit BioSemi Data Format, and preprocessed epoched derivatives are provided in MNE-Python format, enabling research in EEG-to-image decoding and visual neuroscience.

Compute on this dataset

Two routes today, with a third (in-browser one-click submission) landing soon.

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/nm000133), and submit.
nsgportal.org →
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 nm000133
cd nm000133 && nemar dataset get
```
Just the files.
rclone, aria2c, or any HTTPS client works against data.nemar.org/nm000133/ — 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.
