Quickstart#
Install
pip install eegdash
Access the data
from eegdash.dataset import NM000146
dataset = NM000146(cache_dir="./data")
# Get the raw object of the first recording
raw = dataset.datasets[0].raw
print(raw.info)
Filter by subject
dataset = NM000146(cache_dir="./data", subject="01")
Advanced query
dataset = NM000146(
cache_dir="./data",
query={"subject": {"$in": ["01", "02"]}},
)
Iterate recordings
for rec in dataset:
print(rec.subject, rec.raw.info['sfreq'])
