Thanks.
I’ve noticed with the newest stream a few posterior inaccuracies (compared to my previously completed stream). I’ve attached a tiff. You can see the sulcus that is missed. If I am correct, this is a segmentation issue, and one adds control points to help define the white matter intensity?

yes, that is correct. I'm attaching some power point slides that show a block diagram of the new stream.

Newest stream With the most recent release, does the skullstripping take place with brainmask.auto.mgz and brainmask.mgz? After completing recon-all –autorecon-all I checked brain.mgz. I had some frontal areas missing, so ran recon-all -skullstrip -wsthresh 30. Brainmask.mgz looks good.
I believe that I know the answer, but to be safe, after running –autorecon2 brain.mgz will reflect these edits? Thanks, Cliff
