Before revision:  Our approach uses comparison with marmoset fluorescent tracer injection data from the Japan Brain/MINDS to validate and optimize ex-vivo diffusion weighted MRI (DWI)-based global fiber tracking results of the same subject. The approach includes multiple comparisons at a higher-than-DWI resolution standard brain space to evaluate objectives of coverage and passage constraint. The coverage objectives maximize sensitivity while constraining the growth of false positives, promoting the generation of long connections to the projection areas. The passageconstraint minimizes the number of fibers crossing hemispheres outside the commissures .
After revision:  Our approach uses comparison with marmoset fluorescent tracer injection data from the Japan Brain/MINDS Project provides invaluable datasets containing both dMRI and neural tracer data from the same primates. We considered four criteria for goodness of fiber tracking: distance-weighted coverage, true/false positive ratio, projection coincidence, and commissural passage, applied using a multi-objective optimization algorithm .
