Hi professor,

    I am using Freesurfer for DTI data. When I run 'mri_segstats',  I got the result that there was anobvious difference in left hippocampus, but no difference in right hippocampus. Then, I run segmentation of  hippocampus subfields. The result showed there is no difference in total left or right hippocampus, and only in two right hippocampus subfields has significant difference. Why is there inconsistent result in two means? 
    Thank you very much.

Sincerely,
Zheng
