Hi Ayaz,
In addition to the platform differences, DTIstudio uses deterministic tractography algorithm (Fiber Assignment by Continuous Tracking (FACT) method), whereas the TRACULA uses prior information of anatomy surrounding the fiber tracts along with a more sensitive probabilistic crossing fibers algorithm (based on FSL's bedpostX).
Hope this is helpful,
Priti
Hi Ayaz:
Both packages are equally good. The main difference, is that DTI studio runs on Windows while FreeSurfer is Linux/ Unix based. So it depends on your platform. It also depends on your research question/s.
best,

Hi Ayaz
I'm not all that familiar with DTI studio. Tracula, which is a package within FreeSurfer, automically generates models of 17 or so major white matter fascicles with no user intervention required.
cheers Bruce

Dear All,
I am new to freesurfer DTI analysis. Can anybody explain what is the advantage of using freesurfer for DTI analysis over DTI studio?
