Hi Freesurfer team,
I have a question about segmentation. I am working with scans of patients with Down syndrome and the segmentation (aseg.presurf.mgz and aseg.mgz) for a few subjects is slightly inaccurate. It mostly affects the areas that we are specifically interested in - basal ganglia and thalamus. Is there any alternative way to correct the segmentation other than doing it manually?
Thank you!
Best, Anna
Hi Anna
can you send us some images of upload a subject so we can see what you mean?
cheers Bruce

Bruce,
I have uploaded files via FileDrop, I was not able to use freesurfer@nmr.mgh.harvard.edu as a recipient and I used your email instead. Please let me know if you are able to access the files.
Thank you!
