[Mristudio-users] fiber tracking and DTI map between two groups

[yapengw at u.washington.edu]

Hi studio users,
I'm ready to compare whether the FA, RA values and the fibers going through Frontal, ACC and Parietal lobes are different for two groups(A and B).

Right now, I know how to calculate the FA and RA, and to do fiber tracking at the whole brain for single subject, but I do now know how to get the FA and RA values, and fiber tracking resluts at a specific area for single subject and two groups.

It seems that for FA and RA analysis, and fiber tracking, to attain my research purpose, I have to do ROI analysis. Should I draw ROI and do ROI analysis subject by subject, or there is other method to do ROI analysis in an easier way?

When I finish ROI analysis for FA, RA and fiber tracking. How can I know FA and RA values and fiber tracking resluts at a specific ROI? Thank you very much!
