a question was raised whether it is possible to automatically segment anterior
and posterior commissures. Do you think that it is achievable with reasonable
accuracy, using in-vivo data of 0.7 mm3 resolution?
I was thinking what would be the best way:
a) Is it possible to customize Hippocampal subfields segmentation framework to
achieve this goal?
b) I considered the most straightforward option to extend current
RB_all_2016-05-10.vc700.gca atlas to include also labels of anterior and
posterior commisure. However, this would need to have labeled source subjects
for this atlas. Is it publicly available? If yes, do you think that it makes
sense to do it this way?
c) In case of source subjects for RB_all_2016-05-10.vc700.gca are not
available, then there would be option to create the atlas from scratch. Does it
make sense to do it like following:
Take let's say 10 representative subjects, run them through recon-all, take
their aseg.mgz, manually label their commissures (only, other stuff in aseg.mgz
leave as is) and run rebuild_gca_atlas.sh on relabeled aseg.mgz? This (in
contrast to do the manual labeling of whole brain) seems doable to me. I do not
know how the resolution of subjects constituting RB_all_2016-05-10.vc700.gca
was, so maybe doing labeling on our 0.7mm3 subjects could lead to even more
accurate results, than option b)? Could you please comment on?
