Average shape and position of all bundles that are part of the TractEM protocol (association and projection pathways are shown only for the left hemisphere). The average was computed using segmentation from 4 raters and 4 datasets (BLSA) using a majority vote. This highlights the general agreement on the shape, but as seen in the lower right vignette the variability of each individual segmentation can be quite extreme.
