Superficial white matter bundle atlas based on hierarchical fiber clustering over probabilistic tractography data

•We present a new superficial white matter (SWM) atlas of short association bundles created by an unsupervised method based on different levels of fiber clustering, over probabilistic tractography data.•The resulting atlas is composed of 525 bundles of short association fibers along the whole brain, with 384 bundles connecting pairs of different ROIs (cortical circumvolutions) and 141 bundles connecting portions of the same ROI.•The reproducibility of the atlas bundles was verified using an automatic segmentation applied to new subjects from three different tractogram databases, with a high reproducibility found for HCP probabilistic tractography.•Compared to previous whole-brain SWM atlases, our atlas features better cortical surface coverage and a larger number of bundles, with 97 bundles not described in previous atlases (58 in the left hemisphere and 39 in the right hemisphere).
