Hi!  
The row names in the first column of the final.CSV file represent exactly which part of the brain’s fiber bundle? I don’t know what these abbreviations mean. For example, what does “T\_AF\_Left” mean?

Hi!

These are the abbreviations of the anatomical tracts in [the ORG atlas](http://dmri.slicer.org/atlases/). You can look up the full names here:
