Hello~ all~~
I'm processing huge DTI data by FSL in fedora10(linux 64bit)
but, i have a problem in tbss stage 3 (tbss_3_postreg)
i used below command
$ tbss_3_postreg -S
i have the error message like this~~ .

now view mean_FA_skeleton to check whether the default threshold of 0.2
needs changing, when running:
tbss_4_prestats <threshold>

i think this is memory error.
The data i used
Normal : 84 subjects
SVD : 47 subjects
84 vs. 47
Is there any limitation about #of subjects in tbss??
plz solve this problem~!
thank you ~!!!
