Dear all,
I'm running "dtiInit"with SPM8/Matlab 2018a/latest Vistasoft release in windows10 , and having some problems in getting Brain extraction using BET, the following error occurs:
"data will be saved to D:\data\dti_asq\cdn\sub001\dti64trilin.
Computing brain mask from average b0...
saving data as int16...

Warning: Brain extraction using BET failed- using a simple threshold method.

Thank you!
