Re: [Freesurfer] asegstat values pre and post editing

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

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

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

        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. Claudia
