Hello Aaron, 1. The hippocampus is a known area that FreeSurfer has a little difficulty with so we don’t expect perfection in that area. The subject shown in the document is quite good however.
2. Yes, "good" volume distortion has fewer blobs. The blobs are indicating where the individual surface was manipulated in order to register to the atlas. So the fewer manipulations the better. Hope this helps.

In the panel on the lower left corner on page 23 of the data quality slides (https://wustl.app.box.com/s/krekn5svmg4rgig2ossqqhuhcbrgg8c6), is the brain segmentation there missing some parts of the temporal lobe? 2. On page 25 of the slides, what's the criteria of determine "good" or "bad" volume distortion? Fewer number of above-threshold blobs the better? I also have a question about structural connectome of the HCP diffusion data. Is there any shared script to generate parcel to parcel structural connectivity using Dr. Glasser's multi-modal parcellation scheme?
