nm000158 NEMAR-native dataset

Liu, Lv et al. 2023 — EEG datasets of stroke patients (motor imagery)

An EEG motor imagery dataset from 50 acute stroke patients (1-30 days post-stroke) performing left- and right-handed hand-grip imagination tasks. The dataset comprises 40 trials per subject (20 left, 20 right) recorded with a 29-channel wireless EEG system at 500 Hz, including raw and preprocessed data. This is the first open dataset to address bilateral motor imagery in acute stroke patients, providing a critical resource for brain-computer interface algorithm development and clinical rehabilitation 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 nm000158
cd nm000158 && nemar dataset get
```
Just the files.
rclone, aria2c, or any HTTPS client works against data.nemar.org/nm000158/ — 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.
