MRI derived measurements such as brain network measures are inherently discrete and are affected by the resolution of acquisition. Appropriate normalization techniques permit the use of DWI and tractography methods to create measurements that would allow the study of the fibrous structure within the brain. Here we present an edge weight metric used to define the connectivity strength of a network node that would allow a better understanding of local networks in the brain. With this edge weight metric, anatomical structures are defined, i.e. nodes, and the implied white matter tracts from tractography give rise to the edge.
