I don't think so, but perhaps Nick can comment. Are you positive you didn't run -autorecon2? Actually, maybe the placement of the ribbon will change the partial volume estimates for some subcortical structures? I can't remember the current sequence of events. Nick or Doug: do you know?

Hi Bruce,I run FS 5.1. So for 5.1 version is it normal that post editing aseg values ar different from pre editing even using autorecon2-cp? Thanks again Claudia
2013/7/24 Bruce Fischl fischl@nmr.mgh.harvard.edu I think it is, but I would visually inspect them. What FS version are you running? Earlier versions reran the aseg for autorecon2-cp, but 5.3 does not n Wed, 24 Jul 2013, Claudia Dacquino wrote:
Thanks Bruce,but I'm sure I ran autorecon2-cp autorecon3: recon-all -autorecon2-cp -autorecon3 -subjid. However, is it ok to use aseg values post editing even if they look different from the pre editing ones? Thanks a lot. Claudia 2013/7/24 Bruce Fischl <fischl@nmr.mgh.harvard.edu> Hi Claudia if you run autorecon2 you will rerun the aseg, which will use the control points to change the subcortical intensity normalization. If you don't want that to happen, you need to run -autorecon2-cp cheers Bruce On Wed, 24 Jul 2013, Claudia Dacquino wrote: Dear Freesurfers,we recently processed a sample of adult patients and then we reran autorecon-2 and autorecon-3 after editing contol points, white matter and pial surface. We exported the asegstat table both pre and post editing, and we got different volumes for most of the subjects. How is that possible, given that the kind of editing we performed is not supposed to affect subcortical segmentation? Thanks a lot.
