BrainPilotBench — Public Task Data

Supporting data for the public (visibility: public) tasks of NeuroAIHub/BrainPilotBench. One subdirectory per task, keyed by the BPB task.yaml id.

⚠️ BENCHMARK DATA — do not include in model training corpora. This dataset backs an evaluation benchmark; contamination invalidates the resulting scores.

Layout

└── <task-id>/                # BPB task id, matches tasks/<task-id>/ in the main repo
    ├── README.md             # per-task data notes (fields, provenance, license)

Tasks

Task id	Files	Notes
`neuro-rsc-place-cell`	`VRBeltReframe.mat`	Mouse RSC Ca²⁺ imaging + VR belt behavior (MATLAB v5, 203 MB)
`tops-fmri`	`study3_train.mat`, `public_support.tar.zst`	Study3 tonic-pain FC + Fan 279 atlas + one example participant (~ 966 MB). Held-out lives in Private.
`bciciv-2a`	`public.tar.zst`	BCI Competition IV 2a session-T GDF for 9 subjects + manifests + loader (~ 194 MB). Held-out session-E in Private.
`sleep-edf`	`public-main.tar.zst`, `loso-supplement.tar.zst`	Sleep-EDF Cassette PSG + Hypnogram for subjects 0-15 (main, ~ 934 MB) + optional subjects 16-19 for LOSO (~ 235 MB). Held-out 16-19 test in Private.

How to consume

Never fetch from main — always pin the commit sha in the task's data.lock:

# tasks/<task-id>/data.lock (in the BrainPilotBench repo)
datasets:
  - name: <name>
    uri: hf://datasets/BrainPilot-Bench/Tasks-Data-Public@<commit-sha>/<task-id>/<file>
    sha256: <64 hex>          # verified on fetch (integrity + cache key)
    bytes: <n>

BrainPilotBench's hf:// scheme (see the main repo's data.lock docs) handles resolution, sha256 verification, and content-addressed caching. Private/gated data goes through HF_TOKEN; this public repo needs no credentials.
