Dear SPM experts,
I am doing VBM analysis on scans of AD patients and healthy controls. I
just finished the segmentation and found a lot of inaccurate
segmentations, especially in scans with a lot of atrophy. I attached a
screenshot of the segmentation for illustration of the problem. It seems
as if the space between the cortex and the dura is also segmented as
gray matter. I used 'New Segment' of SPM8.
Does anyone have an idea why this happens and how I can solve this
Another issue is, that often the dura around the brain is also segmented
as gray matter. In the older version of the 'Segment' step there was a
'Clean up' option. Does anyone know how to solve this in the 'New
Segment' step of SPM?
Thanks in advance.
