Hi Jay
That sounds fine yes.
Note that typically, uncertainty in orientation within CSF is high, so streamlines will quickly spread and lower voxelwise probability.

When i see the results it shows connectivity streamlines which pass through the ventricles which are filled with CSF(cerebro spinal fluid). The connectivity steamlines seem to easily pass though the CSF because it has high diffusivity profiles in CSF regions. The connectivity streamlines in this case does not make sense while trying to interpret the neuronal connectivity of the brain.
