Atlases available

This tool can be used to visualize the brain areas in the following atlases:

‘Desikan-Killiany’ aparc cortical atlas as present in FreeSurfer [1].
‘Desikan-Killiany’ aparc+aseg combined cortical and subcortical atlas as present in FreeSurfer [1].
120 regions Cammoun sub-parcellation of the Desikan-Killiany cortical atlas [2].
120 regions Cammoun sub-parcellation of the Desikan-Killiany cortical atlas with ASEG subcortical regions [2].
250 regions Cammoun sub-parcellation of the Desikan-Killiany atlas [2].
39 regions combined Walker-von Bonin and Bailey (WBB47) parcellation atlas of the macaque [3][4][5][6].

Installation

Download/clone this repository and save it in a directory, e.g. ~/MATLAB
Locate the simple-brain-plot directory and add this directory to your MATLAB path using the addpath command:

addpath('~/MATLAB/simple-brain-plot')

You are ready to use plotBrain!

Note: When you use the function for the first time, the figure viewer in MATLAB may display "Unable to open file" or "File not found". This error only appears when you use the function for the first time and will be resolved when you try to run it a second time.

Usage

plotBrain(regions, values, cm) creates brain plot with regions having colors as specified by the regions and values vectors with a colormap defined by the matrix cm. Colormap cm can have any number of rows, but must have exactly 3 columns.

plotBrain(regions, values, cm, ...) creates brain plots with optional arguments:

'limits'     Two element vector [cmin cmax]. cmin and cmax are assigned
             to the first and last color in the colormap.
             - default: [min(values) max(values)]
'viewer'     A logical indicating whether the created figure will be opened 
             in web viewer.
             - default: true
'savePath'   A char array with location and first part of the output file name.
             File name will be: ['savePath'_ATLASNAME.svg]
             - default: temporary dir, deleted afterwards.
'scaling'    A scalar specifying scaling of image. Original scaling is very 
             large, but smaller scalings show small white lines
             - default: '0.1' (10%)
'atlas'      Chose which atlas to use
             'aparc'            - Desikan-Killiany atlas
             'aparc_aseg'       - Desikan-Killiany atlas + subcortical ASEG
                                  segmentation
             'lausanne120'      - 120 regions Cammoun sub-parcellation of
                                  the Desikan-Killiany atlas
             'lausanne120_aseg' - 120 regions Cammoun sub-parcellation +
                                  subcortical ASEG segmentation
             'lausanne250'      - 250 regions Cammoun sub-parcellation
             'wbb47'            - 39 regions combined Walker-von Bonin and Bailey
                                  parcellation atlas of the macaque
             - default: 'lausanne120'

Examples

Preparation

First create the colormap you would like to use (one can also use the standard MATLAB colormap). Here we show an example based on the cbrewer YlGnBu-colormap.

cm = [0.8431    0.1882    0.1529; ...
    0.9569    0.4275    0.2627; ...
    0.9922    0.6824    0.3804; ...
    0.9961    0.8784    0.5451; ...
    1.0000    1.0000    0.7490; ...
    0.8510    0.9373    0.5451; ...
    0.6510    0.8510    0.4157; ...
    0.4000    0.7412    0.3882; ...
    0.1020    0.5961    0.3137];
cm = interp1(cm, 1:0.01:size(cm,1));

Make a folder called "figures" in which the generated figures can be saved.

[~, ~] = mkdir('figures');

Load the names of the brain regions for all atlases.

load('regionDescriptions.mat');

Visualize atlases

In this example, brain plots are colored using random values. Replace the random values function randn(size(regionDescriptions.ATLAS)), with your own variable to plot your specific values in the brain figure.

APARC + aseg atlas

plotBrain(regionDescriptions.aparc_aseg, ...
    randn(size(regionDescriptions.aparc_aseg)), cm, ...
    'atlas', 'aparc_aseg', ...
    'savePath', 'examples/figure');

APARC atlas

plotBrain(regionDescriptions.aparc_aseg, ...
    randn(size(regionDescriptions.aparc_aseg)), cm, ...
    'atlas', 'aparc', ...
    'savePath', 'examples/figure');

Lausanne120 + aseg atlas

plotBrain(regionDescriptions.lausanne120_aseg, ...
    randn(size(regionDescriptions.lausanne120_aseg)), cm, ...
    'atlas', 'lausanne120_aseg', ...
    'savePath', 'examples/figure');

Lausanne120 atlas

plotBrain(regionDescriptions.lausanne120_aseg, ...
    randn(size(regionDescriptions.lausanne120_aseg)), cm, ...
    'atlas', 'lausanne120', ...
    'savePath', 'examples/figure');

Lausanne250 atlas

plotBrain(regionDescriptions.lausanne250, ...
    randn(size(regionDescriptions.lausanne250)), cm, ...
    'atlas', 'lausanne250', ...
    'savePath', 'examples/figure');

WBB47 atlas

plotBrain(regionDescriptions.wbb47, ...
    randn(size(regionDescriptions.wbb47)), cm, ...
    'atlas', 'wbb47', ...
    'savePath', 'examples/figure');

Advanced

Center the color axis around 0 using the limits option:

values = randn(size(regionDescriptions.aparc_aseg));
plotBrain(regionDescriptions.aparc_aseg, ...
    randn(size(regionDescriptions.aparc_aseg)), cm, ...
    'atlas', 'aparc', ...
    'limits', [-max(abs(values)) max(abs(values))]);
