The seeds_to_targets mode only saves the probabilities in each seed voxel,
not path distributions for the whole brain. It is useful for comparing the
probability of projection of one region to several others, and segmenting
the seed region according to probability of projection to the targets. If
you want to dissect tracts, you should use the path distribution mode.

Saad,
Thanks for your quick reply.
I have checked the fdt_paths file and it does contain an anatomically
correct tract. The fslstats seeds_to_target -R does show the range from 0 to
1 as expected. I reset the min/max to be 0/1 and only 3 voxels all with the
value of 1 show up. No other voxels with values lower than 1 are contained
in the seeds_to_target image. Is there any reason why so few voxels are
contained in the seeds_totarget when the number of voxels in the fdt_path
image contains a lot of voxels with high intensities.
Thanks for your help
Anastasia
