Quickstart#
Install
pip install eegdash
Access the data
from eegdash.dataset import DS004574
dataset = DS004574(cache_dir="./data")
# Get the raw object of the first recording
raw = dataset.datasets[0].raw
print(raw.info)
Filter by subject
dataset = DS004574(cache_dir="./data", subject="01")
Advanced query
dataset = DS004574(
cache_dir="./data",
query={"subject": {"$in": ["01", "02"]}},
)
Iterate recordings
for rec in dataset:

About This Dataset#
This experiment includes 146 subjects: 98 individuals with Parkinsons disease,
and 48 controls. The data were collected from 2017-2021. Subjects completed this oddball task (along with multiple other cognitive tasks) while EEG was recorded with a 64-channel BrainVision cap. This task includes a primary GO cue, (white arrow) that required a directional response. That response could be correct or incorrect. The primary cue was preceeded by a visual pre-cue and an auditory pre-cue, which occurred at the same time (500ms before arrow cue).
Each trial had either standard for both pre-cues, oddball visual pre-cue, or oddball auditory pre-cue.
Our analysis focused only on trials with both pre-cues standard or oddball auditory pre-cue.

NEMAR Processing Statistics#
The plots below are generated by NEMAR’s automated EEG pipeline. The histogram shows pipeline success for data cleaning and ICA decomposition, the percentage of data frames and EEG channels retained after artefact removal, line noise per channel (RMS, dB), and the age/gender distribution of participants.

Examples
>>> from eegdash.dataset import DS004574 >>> dataset = DS004574(cache_dir="./data") >>> recording = dataset[0] >>> raw = recording.load()
- __init__(cache_dir: str, query: dict | None = None, s3_bucket: str | None = None, **kwargs)[source]#
- save(path: str, overwrite: bool = False, offset: int = 0)[source]#
Save datasets to files by creating one subdirectory for each dataset:
path/ 0/ 0-raw.fif | 0-epo.fif description.json raw_preproc_kwargs.json (if raws were preprocessed) window_kwargs.json (if this is a windowed dataset) window_preproc_kwargs.json (if windows were preprocessed) target_name.json (if target_name is not None and dataset is raw) 1/ 1-raw.fif | 1-epo.fif description.json raw_preproc_kwargs.json (if raws were preprocessed) window_kwargs.json (if this is a windowed dataset) window_preproc_kwargs.json (if windows were preprocessed) target_name.json (if target_name is not None and dataset is raw)
- Parameters:
path (str) –
- Directory in which subdirectories are created to store
-raw.fif | -epo.fif and .json files to.
overwrite (bool) – Whether to delete old subdirectories that will be saved to in this call.
offset (int) – If provided, the integer is added to the id of the dataset in the concat. This is useful in the setting of very large datasets, where one dataset has to be processed and saved at a time to account for its original position.
