Building a volumetric gradient map.

<p>Principal gradient map diagnostics and resulting map. <b>(A)</b> Scaled Eigenvalues across components. <b>(B)</b> A scatter plot of the first and second connectivity-based principal gradients. Each dot in the scatter plot represents connectivity, and different color represents the relationship between the first and second gradients. The gradient pattern was largely consistent with the original study [<a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.3002910#pbio.3002910.ref033" target="_blank">33</a>]. (<b>C)</b> A brain map representing the first and second gradients using the same color scheme as the scatter plot in <b>B</b>.
