a

k = 0.61–0.80 is considered ‘substantial agreement and k = 0.81–1.0 is considered ‘almost perfect’ agreement.

b

CLUST 1 = clustering result by operator 1; CLUST 2 = clustering result by operator 2; MROI 1 = MROI result by operator 1; MROI 2 = MROI result by operator 2

c

CB = cingulum bundle, Genu (of corpus callosum), IFOF = inferior occipitofrontal fasciculus, UF= uncinate fasciculus, ILF = inferior longitudinal fasciculus, AF = arcuate fasciculus, CST = corticospinal tract
