Hi everyone:
I was confuced about the results of my data of probabilistic tractography.
I want looking for the corpus callosum tract, so i find the co-ordinates
(x,y,z)=(62,51,37) on the FA map which i got it using DTIfit. Then i ran
the ProbTrack and got the output "a62_51_37.nii.gz". But the tracking is
strange. It tract to the ventricles rather then the visual cortex.
I use FSL under Windows/Cygwin. And my diffusion data were acquired
from 1.5T GE, b=0/1000, 14 directions with b0).
I was confused because the output of Eddy current and DTIfit are fine. I
don't know where the problem is. I also ran the diffusion data with 56
directions, the output was the same.
the attched file is the fslerrorreport of the sub1.bedpost directory.
Any comments and suggestions please.
