Dear Daniel, Such a script doesn’t exist yet (it’s in the to-do list). The reason why it’s not a straightforward extension of segmentHA_T1.sh is that resampling the anisotropic T2s to a common space is not a good idea, given the differences in orientation. There are ways of getting around this problem; I just haven’t found the time to do it, yet… Cheers, /Eugenio

External Email - Use Caution Hello,
I have recently used segmentHA_T1_long.sh and was pleased with the segmentation results. However, I now have a longitudinal data set that has additional T2 high-resolution scans of the hippocampus as well as T1's. I know there is a segmentHA_T2.sh script to incorporate these types of scans. However, there doesn't seem to be a longitudinal version for this. Is this something that is being worked on? Or is there another reason that T2 should not be used with longitudinal analysis?
Thank you for any advice you can provide,
