FADTTSter w/ TRACULA
Hello,

I am wondering if it is possible to use FADTTSter to analysis the data output from the along the tract analysis for TRACULA; if so I can't find something equivalent in the TRACULA outputs as to arc length. Any ideas? I will also post to the freesurfer forum.

Best,
Alex

Hi Alex

I am not an expert on TRACULA, so please correct me if I am wrong on this, but TRACULA tracks the fiber tracts in individual space, leading to different fiber tracts across subjects. Thus, the number of tracts, the length of the tracts, etc, are all different across subjects. Thus, one would need to create first a correspondence across the tracts of all subjects that currently does not exist. Thus, I don't see a way how TRACULA tracts can be used within FADTTSter. You would need a way to get to profile that are corresponingly sampled.
