Hi Surfers,
I have done some Longitudinal Processing on a bunch of subjects and although the pial and white surfaces are looking good after the Longitudinal Processing, the aseg segmentation for each subject is often looking much worse.
I have attached a sample screen grab to show you what I mean. The images on top show the Longitudinal Processed views. The images on bottom are of the same subject before the Longitudinal Processing has occurred.
It is possible I am doing something wrong. I just thought I would throw it out to the experts to see if they are having similar experiences or if there are suggestions on things that I should do.
Thanks very much,
B.A.

I have a link to a sample screen grab to show you what I mean (see below). The images on top show the Longitudinal Processed views. The images on bottom are of the same subject before the Longitudinal Processing has occurred.

Hi BA,
don't really know what you mean. The slices are slightly different and there are some differences but from these images I cannot say what is more accurate and what is not.
Cheers, Martin
