Initial FCT computation. For the voxel Vi in the brain region of the rs-fMRI data, the process first follows the patch-based correlation measurement strategy to compute the correlation coefficient C′ij, which compares the time courses of voxels in Qi centered at Vi with those in Qj centered at Vj. The dyadic tensor Dij is also prepared to present the directions from Vi to Vj. The FCT Ti is then obtained by computing the sum of all the dyadic tensor with its corresponding correlation coefficients.
