Abstract: Highlights•Propose a method for quantitative evaluation of tractography algorithm performances.•Investigate the effect of the tractography method on connectivity estimation.•Study white matter bottleneck configurations in an ex-vivo macaque brain.•Provide a 59-areas tracer-based connectivity matrix and parcellation for the macaque.
