OpenNEURO for MATLAB

A MATLAB® toolbox for accessing remote datasets stored on OpenNEURO data archive. OpenNEURO only stores BIDS-compliant datasets, so OpenNEURO for MATLAB is also BIDS-aware.

OpenNeuro Matlab Interface — A lightweight interface for inspecting OpenNeuro datasets and reading and processing meaningful subsets in MATLAB.

🚧This is at a first proof-of-concept stage, not yet ready for alpha testing🚧

Usage

>> ds = openneuro.Dataset('ds001415');
>> anatDS = ds.Participantwise('JSON Files');

Input Arguments

• 'dsXXXXX': OpenNeuro dataset ID (e.g., 'ds001415').
• (data type) can be one of the following:

Type	Folder	File Extensions	Read Function
'Anatomical NIfTI'	anat	.nii, .nii.gz	niftiread
'EEG EDF'	eeg	.edf	edfread
'Functional NIfTI'	func	.nii, .nii.gz	niftiread
'DWI'	dwi	.nii, .nii.gz	niftiread
'Fieldmap'	fmap	.nii, .nii.gz	niftiread
'JSON Files'	anat	.json	@(f) jsondecode(fileread(f))
'TSV Files'	anat	.tsv, .txt	readtable

Example: Read a JSON file

if anatDS.hasdata()
    [data, info] = anatDS.read();  % No arguments as required
    fprintf('    ✓ MVP read successful: %s\n', info.Filename);
else
    fprintf('    ✗ No data available (normal if dataset folder doesn''t exist)\n');
end

Requirements

• MATLAB R2023a or later
