This app will generate ROIs that can be used for visual white matter tracking, including optic radiation tracking. This includes visual areas from the Glasser parcellation, the left and right LGNs from a thalamic nuclei segmentation, and exclusion ROIs from freesurfer. The ROIs will be resliced into diffusion space in of this. The Glasser ROIs will be binned by Eccentricity based on pRF mapping
