Hi FreeSurfer Experts,

I have extracted ASEG volumes using "asegstats2table" and have a few questions about the output.

1. I get values of "0" for Left and Right "WM-hypointensities" as well

as "non-WM-hypointensities". Does the ASEG segmentation for WM-hypointensities only produce whole brain measures (Left and Right combined) ?

They are not divided into left and right.

2. Most measures are separated by Left and Right, but some are not.

So, are these values pertinent to both hemispheres (whole brain?)

They certainly could be. I'm not sure about why they are not separated.

3. Is there a reference page I can check to see what each of the

measures mean (i.e. atlas)?

I'm not sure what you mean. Can you be more specific as to which measurements you are talking about?

Thank you for your time!
