nm000151 NEMAR-native dataset

Motor imagery dataset for three imaginary states of the same upper extremity

This dataset comprises EEG recordings from 12 healthy subjects performing three-class motor imagery tasks involving the same upper extremity: rest, right hand grasping, and right elbow flexion. Data were collected across 4 sessions per subject using a 32-channel EGI Geodesic Net system at 1000 Hz sampling rate. The dataset includes 2880 trials total and was designed to evaluate time-domain feature extraction and support vector machine classification for brain-computer interface applications.

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 nm000151
cd nm000151 && nemar dataset get
```
Just the files.
rclone, aria2c, or any HTTPS client works against data.nemar.org/nm000151/ — 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.
