map and use the "thresholding" or "region growing" tool to
define the white matter - cortex boundary with FA = 0.15-0.25. This usually
gives the good white matter surface.<o:p></o:p></span></font></p>

I'am wondering that how to use DTI data to reconstruct the cerebral
cortex surface or WM surface. The DTIStudio seems that can only carriy out
to the fiber-tracking step. Thanks!<br>
