OK I get it. There was a confusion about adding control points and adding new time points. My answer concerns adding new time points, so you can ignore it. Do not add any edited results as new time points.
Concerning your question see the discussion on this list from Feb 12 that treats exactly this topic. In short: - edit the cross sectionals (you have done that) - run the base and edit the base - then the longitudinals should be fine Martin On Wed, 2010-03-10 at 13:08 -0600, Guang Zeng wrote: > Hello, Martin, > > Thanks a lot for your reply, but I am still not very clear about few > issues. > I think that is because of my unclear description. > > What happen is: > I have two scans which I want to do longitudinal analysis, however, > when I finish the > cross-sectional analysis, I found the results are not so good because > of the low contrast > between white matter and gray matter.
