Fig. 5: Illustration of NCT usage to explore network correspondence between two atlases.
From: A network correspondence toolbox for quantitative evaluation of novel neuroimaging results
In this example, we explore overlap between the Yeo2011 17-network atlas (reference atlas) and the Gordon2017 17-network atlas. A The user specifies the name of the reference atlas (here, Yeo2011-17) and the name of comparison atlas (here, Gordon2017-17). The Yeo 17-network atlas is in fsaverage6 space, while the Gordon2017 17-network atlas is in fs_LR_32k. In this case, the reference atlas space is fsaverage6. Therefore, the NCT projects the Gordon2017 17-network to fsaverage6 space. B The NCT computes the Dice overlap between networks from Yeo 17-network atlas and Gordon2017 17-network atlas. The NCT also performs a spin test to test whether networks significantly overlap. C The NCT reports the network correspondence between these two atlases using an overlap heatmap plot, where the k-th row and m-th column represents the Dice overlap coefficient between network k of the Yeo 17-network atlas and network m from the Gordon2017 17-network atlas. A high Dice coefficient indicates high overlap between the two networks. Brighter colors indicate higher overlap, darker colors indicate lower overlap. The “*” indicates two networks significantly overlap (p < 0.05). Most Yeo2011 networks overlap with at least one network in the Gordon2017 atlas. The NCT also provides a summary table showing the exact Dice coefficients and p-values (see Supplementary Table 2). The NCT uses network names from the original paper for each atlas. Dors dorsal, attn attention, sal salience, ven ventral, temp temporal, par parietal, lat lateral, vis visual, med medial, SM somatomotor, cing cingulo, operc opercular, ant anterior, MTL medial temporal lobe.
