Dear Bruce

is there any 3D image file which shows the segmentation regions after this correction ?and if there is not is it right to use aseg.mgz file for reporting Dice or Jaccard Index (I have manual segmentation as gold standard)?

Best Regards,
Nazanin

Dear FreeSurfers,
I have a question about aseg file. I load the aseg file of bert subject in
itk-snap and read the volume for 17 and 53 label but it is a bit larger of
the volume in bert stats file. I do the same for some of my subjects too and
I see the same result .I don't know why it is like that ?would you please
clear the reason for me.because I need to  compare the FreeSurfer result and
I should use of aseg file labels but I'm afraid the comparison I'm doing is
not valid.   

Sincerely yours,
Nazanin
