Quickstart#

Install

pip install eegdash

Access the data

from eegdash.dataset import DS005907

dataset = DS005907(cache_dir="./data")
# Get the raw object of the first recording
raw = dataset.datasets[0].raw
print(raw.info)

Filter by subject

dataset = DS005907(cache_dir="./data", subject="01")

Advanced query

dataset = DS005907(
    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 (3-armed bandit) with alcohol vs. beverage cues in N=53 Community participants. Data collected from 2019-2021 in the CRCL at UNM. The paper [Campbell, E., Singh, G., Claus, E.D., Witkiewitz,K., Costa, V.D., Hogeveen, J; & Cavanagh, J.F. Electrophysiological markers of aberrant cue-specific exploration in hazardous drinkers] Should be coming out in print soonish. Your best bet for understanding this task would be to read that paper first. For more info on triggers and outputs, see BEH_EXPLAIN.m file in code folder. - James F Cavanagh 03/06/2023

API Reference#

Use the DS005907 class to access this dataset programmatically.

class eegdash.dataset.DS005907(cache_dir: str, query: dict | None = None, s3_bucket: str | None = None, **kwargs)[source]#

Bases: EEGDashDataset

OpenNeuro dataset ds005907. Modality: eeg; Experiment type: Learning; Subject type: Alcohol. Subjects: 53; recordings: 53; 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.
