Dear FSL users,
we ran tbss on several subjects and also bedpostx/probtrackx to do tractography between one part of the corpus callosum and different regions of the cortex.
Computing the average number of samples between the seed and each cortical region, we found a negative correlation between global mean skeleton FA and number of samples for each cortical region.
Is it normal to have this kind of negative correlation and how can we explain it?
Thanks,
Hervé Lemaître
