Thank you very much for fast response!
I just checked my data and found something confused me. My input data is ANALYZE files. It showed "LPI" and "Radiologically". Did it mean my input data is uncorrected in orientation?
Thanks, again!

Hi,
We *strongly* advise you to change the handedness of your original
data before
using FSL, as the LPI format (which we term "neurologically stored")
can cause
problems with some FSL commands. To change the way the data is
stored, see
the FAQ entry at:
http://www.fmrib.ox.ac.uk/fslfaq/#general_fslorient
and run the fslswapdim and fslorient commands for each input file in
LPI form.
I'm afraid that you will then need to re-run tbss once you've done
this, but it is
the best way to be sure that your data orientation is OK.
All the best,
Mark
