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
