Quickstart#

Get Started

Install

pip install eegdash

Access the data

from eegdash.dataset import DS005284

dataset = DS005284(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 = DS005284(cache_dir="./data", subject="01")

Advanced query

dataset = DS005284(
    cache_dir="./data",
    query={"subject": {"$in": ["01", "02"]}},
)

Iterate recordings

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

About This Dataset#

1.Study introduction: First, participants underwent a series of laser stimulations of varying intensities. The experimenter determined the energy intensity corresponding to an average score of 7 points among the participants. Subsequently, each participant received a fixed-intensity laser stimulation approximately every 20 seconds, for a total of 16 trials, during which they provided pain ratings ranging from 0 to 10. A rating of 0 indicated no sensation, 4 denoted the onset of pain perception, 6 represented moderate pain, 8 indicated severe pain, and 10 signified intolerable pain. 2.Participant task information(description of the experiment): Participants received laser stimulation and used a computer mouse to click on the appropriate position on the screen, corresponding to a scale of 0 to 10. 3.Participant instructions(as exact as possible): Participants were instructed to concentrate on the laser stimuli, maintain open eyes, and fixate their gaze on a cross displayed on the screen before them. Following the presentation of each laser stimulus, there was a pause of 3�C5 seconds. Subsequently, participants orally rated the intensity of pain within a time window of 3�C5 seconds for each rating. The subsequent trial commenced randomly within 1�C3 seconds after the ratings were provided. 4.References and links: Lu X, Thompson WF, Zhang L, Hu L.

class eegdash.dataset.DS005284(cache_dir: str, query: dict | None = None, s3_bucket: str | None = None, **kwargs)[source]#

Bases: EEGDashDataset

OpenNeuro dataset ds005284. Modality: eeg; Experiment type: Unknown; Subject type: Unknown. Subjects: 26; recordings: 26; 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.
