The vector field should have vectors as voxels , the ROI is an integer image, fibers out will be vtk text files .... ROI-Mask controls where the integration is performed and the start point region ... e.g. the brain will have value 1 , the ROI has value 2 , then all starting seed points for the integration will start in the region labeled 2 and be constrained to the region labeled 1.
