A closer look at the cluster in the right anterior CC that appears under the ‘MaxFA’ strategy but has no equivalent under the tensor averaging strategy. The location of the cluster in question is outlined on the medial surface of the CC. The medial manifold is colored by the relative position along the spokes of the tensor with maximal FA. Positive values (red) indicate that on average, the maximal FA tensor is located on the side of the medial manifold away from the midsagittal plane;. negative values indicate that maximal FA tensors tend to be located one the side facing the midsagittal plane; and values close to zero indicate no bias in the location of the maximal FA tensor. The lateral ventricle is in close proximity to the cluster, which may help explain why tensor averaging, which is more prone to partial volume errors, is less sensitive in this region.
