Download Data

For the tutorials in this book, we will use partially-preprocessed data from two open multi-echo datasets: Euskalibur and Cambridge. For more information about these datasets, see Open Multi-Echo Datasets.

import os
from pprint import pprint

from tedana import datasets

DATA_DIR = os.path.abspath("../data")

euskalibur_dataset = datasets.fetch_euskalibur(
    n_subjects=5,
    low_resolution=False,
    data_dir=DATA_DIR,
)
pprint(euskalibur_dataset)

cambridge_dataset = datasets.fetch_cambridge(
    n_subjects=5,
    low_resolution=False,
    data_dir=DATA_DIR,
)
pprint(cambridge_dataset)

For now, we will use repo2data to download some data we’re storing on Google Drive.

import os

from repo2data.repo2data import Repo2Data

# Install the data if running locally, or point to cached data if running on neurolibre
DATA_REQ_FILE = os.path.join("../binder/data_requirement.json")

# Download data
repo2data = Repo2Data(DATA_REQ_FILE)
data_path = repo2data.install()
data_path = os.path.abspath(data_path[0])
