Hi,
I am using TBSS to analyze my DTI data and recently upgraded to FSL4.1. I
saw that the new tbss_1_preproc program attempts to remove scalp and CSF.
However, it is doing it somewhat aggressively removing parts of major WM
fibers. It has become especially problematic in pathways such as fornix. It
had been wiped out completely from a majority of my FA maps, thus excluded
from analysis. Is there a way to turn this masking off? I was doing much
better before, when I was using FSL 4.0. I was using BET to remove non-brain
material and running TBSS without any problems.
Since there are several improvements in 4.1, I do not want to go back to
4.0. So, if there is a way to disable that masking, that would be great.
Thanks,
Tugan Muftuler
