Quickstart#

Get Started

Install

pip install eegdash

Access the data

from eegdash.dataset import DS004152

dataset = DS004152(cache_dir="./data")
# Get the raw object of the first recording
raw = dataset.datasets[0].raw
print(raw.info)

Query & Filter

Filter by subject

dataset = DS004152(cache_dir="./data", subject="01")

Advanced query

dataset = DS004152(
    cache_dir="./data",
    query={"subject": {"$in": ["01", "02"]}},
)

Iterate recordings

for rec in dataset:
    print(rec.subject, rec.raw.info['sfreq'])

About This Dataset#

Drum Trainer

Twenty-one participants learned to play two drumming patterns (pattern 1: AABA, pattern 2: AAABAA) at three different tempos (fast: 150 bpm, medium: 100 bpm, slow: 60 bpm). Responses were recorded using the f and j keys on a standard keyboard. Visual feedback in the form of a coloured circle coincided with each button press and indicated whether the response was early, on time, or late. Feedback was determined by comparing the response time, relative to the previous response, to a window around the target duration. The window was adapted trial-by-trial to ensure that roughly half the outcomes were “on time”.

Participant 12 should be excluded from event-locked analyses due to bad triggers (trigger cable was partially disconnected).

Timing Repeat for 72 trials: fixation dot (until response) -> feedback circle (50 ms)

API Reference#

Use the DS004152 class to access this dataset programmatically.

class eegdash.dataset.DS004152(cache_dir: str, query: dict | None = None, s3_bucket: str | None = None, **kwargs)[source]#

Bases: EEGDashDataset

OpenNeuro dataset ds004152. Modality: eeg; Experiment type: Learning; Subject type: Healthy. Subjects: 21; recordings: 21; tasks: 1.

Parameters:

cache_dir (str | Path) – Directory where data are cached locally.
query (dict | None) – Additional MongoDB-style filters to AND with the dataset selection. Must not contain the key dataset.
s3_bucket (str | None) – Base S3 bucket used to locate the data.
**kwargs (dict) – Additional keyword arguments forwarded to EEGDashDataset.

data_dir#

Local dataset cache directory (cache_dir / dataset_id).

Type:: Path

query#

Merged query with the dataset filter applied.

Type:: dict

records#

Metadata records used to build the dataset, if pre-fetched.

Type:: list[dict] | None

Notes

Each item is a recording; recording-level metadata are available via dataset.description. query supports MongoDB-style filters on fields in ALLOWED_QUERY_FIELDS and is combined with the dataset filter. Dataset-specific caveats are not provided in the summary metadata.
