Re: [Freesurfer] Training Tracula to add more pathways

[Yendiki, Anastasia]

Hi Kris - The tracts have to be labeled manually in a set of subjects, that 
TRACULA uses as its training data. It takes the manually labeled tracts and the 
anatomical segmentation of each of the training subject and it computes the 
probability that a tract will go through or next to each segmentation label as 
a function of position along the tract's trajectory. These are used as prior 
probabilities to find the tracts in any new subject without doing manual 
labeling.

Best,
Anastasia.

Subject: [Freesurfer] Training Tracula to add more pathways

Hi there,

As a complete newbie to the Tracula tool, I have a questions about using it. Is 
it possible to train tracula to track additional pathways other than the 18 
thats are already included? I was to track several pathways that are not 
included with Tracula.

Best,

Kris
