# BIDS for MATLAB / Octave

This repository aims at centralising MATLAB/Octave tools to interact with

BIDS (Brain Imaging Data Structure) datasets.

For more information about BIDS, visit https://bids.neuroimaging.io/.

See also [PyBIDS](https://github.com/bids-standard/pybids) for Python and the

[BIDS Starter Kit](https://github.com/bids-standard/bids-starter-kit).

## Installation

### Requirements

BIDS-MATLAB works with:

- Octave 5.2.0 or newer

- MATLAB R2014a or newer

We aim for compatibility with the latest stable release of Octave at any time.

Compatibility can sometimes also be achieved with older versions of Octave but

this is not guaranteed.

For MacOS and Unix system, using `bids.copy_to_derivative` requires

a version of gunzip >= 1.6.

### Download or clone

Download, unzip this repository and add its content to the MATLAB/Octave path.

```Matlab

unzip('https://github.com/bids-standard/bids-matlab/archive/main.zip');

addpath('bids-matlab-main');

```

Or clone it with git:

```bash

git clone https://github.com/bids-standard/bids-matlab.git

```

and then add it to your MATLAB/Octave path.

```Matlab

addpath('bids-matlab');

```

### Get the latest features

Stable versions should be fetched from a specific version tag

or from the [Mathworkds file exchange](https://nl.mathworks.com/matlabcentral/fileexchange/93740-bids-matlab).

A new version of BIDS matlab should be released for each new version of the BIDS specification

to allow for a support of new BIDS datatypes or features.

If you want the latest features of bids-matlab

that are in development are in our `main` branch.

To access them you can either download the `main` branch from there:

https://github.com/bids-standard/bids-matlab/tree/main

Or clone it:

```bash

git clone --branch main https://github.com/bids-standard/bids-matlab.git

```

## Features

### What this toolbox can do

- read the layout of a BIDS dataset (see `bids.layout`),

- perform queries on that layout to get information about the subjects,

  sessions, runs, modalities, metadata... contained within that dataset (see

  `bids.query`),

- parse the layout of "BIDS-derivative compatible" datasets (like those

  generated by fMRIprep),

- create BIDS compatible filenames or folder structures for raw or derivatives

  datasets (`bids.File`, `bids.util.mkdir`,

  `bids.dataset_description`),

- do basic copying of files to help initialize a derivative dataset

  to start a new analysis (`bids.copy_to_derivative`),

- generate a human readable report of the content of BIDS data set containing

  anatomical MRI, functional MRI, diffusion weighted imaging, field map data

  (see `bids.report`)

- `bids.diagnostic` creates summary figures listing:

  - the number of files for each subject / session and imaging modality

  - the number of trials for each trial type in each events.tsv file for a given task

- read and write JSON files (see `bids.util.jsondecode` and

  `bids.util.jsonwrite`) provided that the right

  [dependencies](#reading-and-writing-json-files) are installed,

- read and write TSV files (see `bids.util.tsvread` and `bids.util.tsvwrite`)

- access and query the [BIDS schema](https://bids-specification.readthedocs.io/en/latest/schema.json) (`bids.schema`)

- access, query and create basic transformations for the [BIDS statistical model](https://bids-standard.github.io/stats-models/) (`bids.Model` and `bids.transformers`)

The behavior of this toolbox assumes that it is interacting with a valid BIDS

dataset that should have been validated using

[BIDS-validator](https://bids-standard.github.io/bids-validator/). If the

Node.js version of the validator is

[installed on your computer](https://github.com/bids-standard/bids-validator#quickstart),

you can call it from the matlab prompt using `bids.validate`. Just be aware that

any unvalidated components may produce undefined behavior. Although, if you're

BIDS-y enough, the behavior may be predictable.

### What this toolbox cannot do... yet

- generate human readable reports of the content of BIDS data with EEG, MEG,

  iEEG, physio and events data,

### What will this toolbox most likely never do

- act as a Matlab / Octave based BIDS-validator

- act as a BIDS converter

- implement reading / writing capabilities for the different modality-specific

  data format that exist in BIDS (`.nii`, `.eeg`, `.ds`, `.fif`...)

## Usage

BIDS matlab is structured as package, so you can easily access functions in subfolders

that start with `+`.

To use the `+bids/layout.m` function:

```Matlab

BIDS = bids.layout('/home/data/ds000117');

bids.query(BIDS, 'subjects')

```

To use the `+bids/+util/jsondecode.m` function:

```Matlab

content = bids.util.jsondecode('/home/data/some_json_file.json');

```

## Demos

There are demos and tutorials showing some of the features in the `demos` folder.

### Reading and writing JSON files

Make sure to be familiar with the [JSON 101](https://bids-standard.github.io/stats-models/json_101.html).

Note some of the perks of working with JSON files described

on [the BIDS starterkit](https://bids-standard.github.io/bids-starter-kit/folders_and_files/metadata.html#interoperability-issues).

For BIDS-MATLAB, if you are using MATLAB R2016b or newer, nothing else needs to be installed.

If you are using MATLAB R2016a or older, or using Octave, you need to install a

supported JSON library for your MATLAB or Octave. This can be any of:

- [JSONio](https://github.com/gllmflndn/JSONio) for MATLAB or Octave

- [SPM12](https://www.fil.ion.ucl.ac.uk/spm/software/spm12/)
