It's under review! In short, this is not a purely data driven approach.
It's data + prior info on the anatomy of the tracts derived from a
manually labeled set of subjects. The prior info is the anatomical
segmentation labels that surround the tract. So the knowledge that the
neuroanatomist w
Hi Anthony
we are trying to get that piece of it published :) Hopefully soon!

Good points Bruce. I guess I am more worried about the people using it,
who will not be as cautious for large datasets. Also--one thing that was
a huge benefit for the cortical parcellation was a quantification of the
manual vs. automated parcellation differences, but this does not appear

Hi Anthony
we included the tracts that we found that we could segment reliably, under
the guidance of a trained neuroanatomist. Certainly we can only do as well
as the information contained in the diffusion data, but we have found that
we can automated what someone with neuroanatomical experti
Hello Anastasia,
This just reinforces my point. Tracts #7 and #8 of that paper are the
inferior longitudinal fasciculus and the inferior occipitofrontal
fasciculus, respectively. But you have chosen to leave one out
(incidentally, both appear in the Oishi atlas). Note that in this paper,

Hi Anthony - The labeling was done based on Wakana et al 2007. We did not
include the IFOF exactly b/c of the controversy surrounding it.

Hello all,
Is there any atlas to which these tracs are referenced? For cortical
anatomical boundaries there is broad consensus and a published
referenced atlas, which makes Freesurfer's automatic parcellation of
cortical regions an excellent tool. But there is not (as is often
assumed) as bro
Hi Anastasia,
Thanks for getting back to me and well done on making a very nice program.
The first tracts I would like to have are the optic radiations, but there
are others that would be nice to include: a three part arcuate fasiculus (a

Hi Seán - Which tracts do you want to add? Our existing tracts have been
labeled on 33 healthy subjects. It's certainly possible to include new
tracts in the atlas but someone has to do the labeling on the same or a
similar set of subjects.

Hi FreeSurfing Gurus,
I would like to add some new tracts to the Tracula pipeline using my own
regions of interest. What would be the best way to do this?
All the best and many thanks in advance,
Seán
