Guang,
So you did not get output that looked like this?
logging overall Dice to text Jaccard Coefficients: correct ratio for label 2 = 1 correct ratio for label 41 = 1 . . correct ratio for label 44 = 1 mean +/- std = 1.0000 +/- 0.0000 Dice Coefficients: label 2 = 1 label 41 = 1 . . . label 44 = 1 mean +/- std = 1.0000 +/- 0.0000 Overall subcortical dice = 1.0000
(in this example, i compared the same aseg, so dice will be 1).
also, make sure your second time point aseg is registered to the first. if it is not, the your dices will be low, because its just comparing voxel to voxel.

Hi, there,
I have two subjects from two time points, I'd like to compare their overlap ratio of FreeSurfer segmented hippocampus. I try to use the command mri_compute_seg_overlap to do it,
My command line is: mri_compute_seg_overlap -olog text tp1/mri/aseg.mgz tp2/mri/aseg.mgz
Is it correct? I ran it, but nothing happen.
Thanks!
Guang
