Hi Ruth - If you apply the same mask to all the volumes in the DWI series,
it's not a problem. The important thing is not to have applied any
operation that would change the intensities of the images inside the
brain. So these should N
moved.

Hi Ruth - Glad to hear this is useful to you. The rotation and translation
parameters are extracted from the affine registration of each DWI volume
to the first volume, which in trac-all is performed by eddy_correct.

Hi Vincent - That is correct. The average values of FA/MD/RD/AD in
pathstats.byvoxel.txt are averaged over all the sampled paths for that
subject at equivalent positions along the trajectory of the path. Roughly
speaking, if 0<=s<=1 is the arc length along the path, where s=0 is the

Hi Anastasia,
Thanks for the new features! The first one helps me a lot!! When looking
at 2., I realized I had not understood the Avg values in pathstats.byvoxel.
The non-Avg values are just the measures at each of these voxels on the
MAP, ok. But then it says
