ball_squeeze_2025

Ball squeeze fNIRS dataset containing functional near-infrared spectroscopy recordings during a ball squeezing motor task. This is a raw neuroimaging dataset with fNIRS data collected from participants performing repetitive ball squeeze movements. The dataset includes SNIRF format data files, task event markers, and associated metadata. Approved by Boston University IRB 4502. For complete dataset information including authors and funding details, see the source OpenNeuro dataset (ds006903).

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/on006903), 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 on006903
cd on006903 && nemar dataset get
```
Just the files.
rclone, aria2c, or any HTTPS client works against data.nemar.org/on006903/ — 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.
