Hi Douglas

Thanks a lot for your answer. I will definitely do that. Can you tell me how I load this aseg.stats file into Matlab? I do not have FreeSurfer downloaded on my own computer. Do I need that to load this file?

-Leise.

Why not just use the values in aseg.stats?

Hi FreeSurfer

I am working on a project concerning Alzheimer’s patients and I need

to know the positions of white matter (WM) and white matter lesions

(WML) from your segmentations.

To find the WML, I use label 77 in the aparc.a2009s+aseg.mgz-files.

To find the WM, I use labels 2 and 41 in the ribbon.mgz-files and

subtract the ventricles by subtracting labels: 4, 5 14, 15, 43 44

found in the aseg.mgz-files.

However, in the two sets of positions – one for WML and one for WM

–there is an overlap. It is not big, but it is there.

Can you help me finding the true WML- and WM-segmentations?

With kind regards, Leise.
