New files provide the length of fiber connectionsPosted By: Konstantinos Arfanakis - Jul 29, 2020
Tool/Resource: IIT Human Brain Atlas (v.5.0)
New files providing the length of fiber connections of the IIT Human Brain Atlas have been added (IIT_WM_atlas_length.nii.gz and IIT_WM_atlas_length_256.nii.gz). These files demonstrate that the top layers of the multi-layer connectivity-based white matter labels DO NOT correspond to longer connections compared to lower layers (over-representation of long tracts is a known tractography concern). The top layers of the IIT Human Brain Atlas do not over-represent longer connections. The new files serve as a sort of quality check of the connectivity information the atlas is based on. A detailed description of the contents of the new files is provided in the updated manual.
