Dear List,
I recently posted the message you see below.
I currently compare the segmentation results of different
segementation algorithms and FreeSurfer always yields the least
accurate results. Because I still have difficulties to decide which
of the labels in the aseg.mgz files should be considered gray
matter, I have the feeling, the bad results I am getting for
FreeSufer might be caused by not including all relevant gray matter
segments.
So, I would very much appreaciate any help on deciding which of the
labels in the aseg.mgz file belong to gray matter!
With kind regards

Dear Experts,
I would like to generate a gray matter mask using the aparc+aseg.mgz file.
Now, my question is whether there exists a file in addition to the
FreeSurferColorLUT.txt
file, which more explicitly, i. e., withouth the abbreviations, explains
the labels, because I
find it hard to decide whether, e. g., "Left-VentralDC", "Line1",
"LeftmOg", or "Left-Interior"
belong to gray matter, or not (to name only a few of those labels I
cannot clearly classify).
Or is there a easier way to create a gray matter mask?
Thank you very much in advance!
Best regards,
Lucas Eggert
