EEG: DPX Cog Ctl Task in Acute Mild TBI

This dataset contains EEG recordings from a Dot Probe Continuous Performance Task (DPX) examining cognitive control in individuals with acute and sub-acute mild traumatic brain injury (mTBI) compared to healthy controls. Data were collected across three longitudinal sessions spanning from 3 days to approximately 4 months post-injury, with substantial subject attrition over time. The dataset was collected between 2016-2018 at the Center for Brain Recovery and Repair, UNM Health Sciences Center, to study neural correlates of cognitive control deficits following mild brain injury.

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/on005114), and submit.

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 on005114
cd on005114 && nemar dataset get
```
Just the files.
rclone, aria2c, or any HTTPS client works against data.nemar.org/on005114/ — 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.

How to download

The dataset: nemar dataset download on005114 Clones and fetches in one step. Content under stimuli/ and derivatives/ is skipped by default because those trees can be large; add --stimuli --derivatives for the whole thing.
A subset, one step: nemar dataset download on005114 --subjects sub-01,02 Also filters by --sessions, --tasks, --runs, --datatypes, --include and --exclude.
A subset, step 1: nemar dataset clone on005114 Clones git-annex pointers only; fetches no file content. Creates ./on005114.
A subset, step 2: cd on005114 The get command below reads the clone's annex, so it only works from inside the clone.
A subset, step 3: nemar dataset get <files> Pulls the files you actually need. Skips stimuli/ and derivatives/ unless the path you ask for is under one of them.
One small file: https://data.nemar.org/on005114/v1.0.0/participants.tsv A direct HTTPS fetch works for any single file.
