I would not expect the different subjects to be the same (they are
different subjects). I don't know how you'd get them back to native
space. The opposite of how you normalized them I guess.

Hi,
I'm new to this and was wondering if someone could help me out?
I used a T1 preprocessed image (fmriprep), normalized to the NIH
pediatric cohort 6 (13-18.5 years) template to do recon-all and then
used the hippocampal segmentation tool v.7.
I have two questions: a) wouldn't one expect the segmentation to be
the same for different individuals if the normalized T1's are used
(registration seems to be well aligned to the same space when checked
in SPM but when looking into the .txt files the volumes are
different)? and b) (how) do I need to use the -custom-tal-atlas flag
to get the estimates back to the NIH pediatric atlas (cohort 6) and
can I make masks from the hippocampal segmentations for ROI analysis
in other software for this study population?
Thank you!
