Symmetrical ROIs using spherical packing algorithm

<p>This is a set of symmetrical regions of interest (ROIs) defined using spherical packing algorithm. These ROIs were used to calculated functional connectivity lateralization index in our paper tittled "Lateralized Resting-state Functional Connectivity in the Task-positive and Task-negative Networks". http://online.liebertpub.com/doi/abs/10.1089/brain.2013.0215</p>
