02. Read and load datasets in BIDS format

When working with neural data in the BIDS format, we usually have varying types of data, which can be loaded in via read_raw_bids function.

• MEG

• EEG (scalp)

• iEEG (ECoG and SEEG)

• the anatomical MRI scan of a study participant

In order to check if your dataset is compliant with BIDS, you can first run the BIDS validator online.

In this tutorial, we show how read_raw_bids can be used to load any BIDS format data, and to display the data that is saved within the accompanying sidecars.

# Authors: Adam Li <adam2392@gmail.com>

We are importing everything we need for this example:

import os

import mne
from mne.datasets import somato

from mne_bids import make_bids_basename, read_raw_bids
from mne_bids.utils import print_dir_tree

We will be using the MNE somato data, which is already stored in BIDS format. For more information, you can checkout the respective example.

# get MNE directory w/ example data
mne_dir = mne.get_config('MNE_DATASETS_SAMPLE_PATH')

Step 1: Download/Get a BIDS dataset

Get the MNE somato data

bids_root = somato.data_path()
somato_raw_fname = os.path.join(bids_root, 'sub-01', 'meg',
                                'sub-01_task-somato_meg.fif')

subject_id = '01'
task = 'somato'
kind = "meg"

bids_basename = make_bids_basename(subject=subject_id, task=task)

# bids basename is nicely formatted
print(bids_basename)

Out:

sub-01_task-somato

Print the directory tree

print_dir_tree(bids_root)

Out:

Step 2: Read a BIDS dataset

Let’s read in the dataset and show off a few features of the loading function read_raw_bids. Note, this is just one line of code.

bids_fname = bids_basename + "_{}.fif".format(kind)
raw = read_raw_bids(bids_fname, bids_root, verbose=True)

Out:
