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 broad a
consensus on white matter tracts (e.g., there is no middle longitudinal
fasciculus in the recent Oishi et al. white matter atlas and many would
argue it doesn't exist; the existence of separate inferior longitudinal
fasciculus and inferior occipitofrontal fasciculus is disputed; Catani's
arcuate fasciculus is based on one paper etc.). Is it such a good idea to go
automatically identifying white matter tracts without saying how they are
identified?

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 la Catani et al.,
2005) rather than a 2 part one, Fornix, anterior commissure.
If I were to manually do the dissections for the 33 subjects,
what would be the most Tracula compatible way of doing it? I
normally use TrackVis but I figure making all of the file
conversions might be a nightmare. Which program was used in the
original virtual dissections?
Any further suggestions? Perhaps some of these tracts are
included but I've missed them.

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
