This MATLAB function enables detailed white matter analyses to be performed based on the combination of labeled T1-weighted structural images, coregistered diffusion parameter maps, and tractography. The function is designed to work with the outputs of BrainSuite. Specifically, we provide capabilities to select specific groups of fiber tracks based on whether or not they pass through specific anatomical ROIs, to define volumetric white-matter ROIs that correspond to selected track groups, and to quantify the volumes and average diffusion parameters of these volumetric ROIs. The combination of this function with the multi-modal processing capabilities of BrainSuite helps to automate and simplify the quantification of specific white matter fiber tracts, and should be particularly useful for longitudinal and/or multi-subject analyses. Figure 1 below illustrates the workflow of the function via Brainsuite GUI.
