Quickstart#

Get Started

Install

pip install eegdash

Access the data

from eegdash.dataset import DS003753

dataset = DS003753(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 = DS003753(cache_dir="./data", subject="01")

Advanced query

dataset = DS003753(
    cache_dir="./data",
    query={"subject": {"$in": ["01", "02"]}},
)

Iterate recordings

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

About This Dataset#

RL task in N=25 college age participants. Data collected circa 2019 in the CRCL at UNM. The paper [Brown, D.R., Jackson, T.J. & Cavanagh, J.F. The Reward Positivity is sensitive to affective liking] Should be coming out in Cognitive, Affective, & Behavioral Neuroscience. THIS IS EXPERIMENT #2. Your best bet for understanding this task would be to read that paper first. Note we have since made minor adjustments to the task which really enhance the ability to resolve the RewP. I also have analytic scripts for it. If you are interetsted in running this task, contact me for the new version. - James F Cavanagh 07/02/2021

API Reference#

Use the DS003753 class to access this dataset programmatically.

class eegdash.dataset.DS003753(cache_dir: str, query: dict | None = None, s3_bucket: str | None = None, **kwargs)[source]#

Bases: EEGDashDataset

OpenNeuro dataset ds003753. Modality: eeg; Experiment type: Learning; Subject type: Healthy. Subjects: 25; recordings: 25; 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.
