Hello Folks,
I used the recon-all -i -all -segmentation for the structural image. FreeSurfer makes several folder and one of them is "stats". In this folder, there is aseg.stats that includes volume of different brain regions. Also, I found "mri_segstats" command line that gives us the volume of the same brain regions. But, there is significant difference between reported numbers from these two methods . I would say the difference is approximately 200 mm3 for each brain region. Do you know what is correct way to measure volume of segmented brain regions using FreeSurfer?
Cheers, Saeed
