Hi Anand,
I got exactly the same error with the default values and with Edge Constant=0.63 and Erosion Size=2.
Except that in the second case (modified values), the pole of the frontal lobes is missing.
I removed this line from the tutorial because modifying these values was giving results that were worse than with the default values.
The file that should be processed in this tutorial is the following (I fixed the download link):
ftp://neuroimage.usc.edu/pub/auditory_tutorial_T1.zip
Right now I cannot use BrainSuite 16a on Windows 10 because the SVReg step is not working.
