Chisco

Chisco is a Chinese imagined speech EEG dataset comprising recordings from five participants across multiple sessions. The dataset includes raw EEG data collected over 5-6 days per participant, along with preprocessed data in both fif and pkl formats. This resource supports research in brain-computer interfaces and speech imagery decoding, with accompanying text stimuli used during data collection. Note: Participants sub-01 to sub-03 follow BIDS 1.6.0 protocol, while sub-04 and sub-05 (supplementary data) follow an earlier BIDS protocol version to maintain consistency with original publications. Future releases (Chisco 2.0) will include data from sub-06 and sub-07 under a new experimental paradigm.

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/on005170), 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 on005170
cd on005170 && nemar dataset get
```
Just the files.
rclone, aria2c, or any HTTPS client works against data.nemar.org/on005170/ — 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.
