Mosaic of dissections of the first timepoint of the first HCP subject from 20 raters (left), all dissections look extremely similar. On the right, the average dissection (gold standard) in both the streamlines and the voxel representations. The coloring is based on the orientation of each streamline, where the X/Y/Z differences are mapped to R/G/B. To be considered part of the gold standard, elements had to be labeled in at least 50% of dissection associated with each subject. The PYT had a more consistent spatial coverage compared to the first Tractostorm project (only bundle in common)
