I'm not sure where the differences are coming from, but it sounds like the range we are seeing. My guess is that the intensity normalization changes are the cause. There are always voxels on the edge of a structure that are ambiguous, and a slight change in intensity can cause their segmentation to switch.

I recently installed version 7.1, and I compared absolute volumes with version 6.0, and I realized that there are some significant differences in some brain structures (e.g. Hippocampus and amygdala). In some cases, the differences are more than 7%-14%. I understand that I should not be mixing the version when I process my datasets, but can you let me know what the main reason for the differences is, and how much should I expect?
thank you. Sang
