Hi - if the initial image orientations are not axial or the images
are a cut-down FOV then sometimes the IRTK registration can fail.
Might this explain it?
The tbss_2_reg.e12345.6 etc files are just log files so you don't
need to copy them.
What happens if you run
fslinfo all_FA
fslstats all_FA -r -R
in the stats directory? Does it have the right number of timepoints?
Cheers.
