Color Change Detection Task

A color change detection task dataset organized in BIDS format containing intracranial electrophysiological (iEEG) recordings from participants performing a visual perception task. Participants were required to detect color changes in visual stimuli while neural activity was recorded from implanted electrodes. The dataset includes raw iEEG data, electrode localization information, and task event markers, organized according to the iEEG-BIDS specification. This standardized format facilitates reproducible analysis and sharing of human intracranial brain imaging data. For complete attribution and dataset documentation, please refer to the dataset files and associated publications.

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/on005624), 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 on005624
cd on005624 && nemar dataset get
```
Just the files.
rclone, aria2c, or any HTTPS client works against data.nemar.org/on005624/ — 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.
