Freesurfer experts:

I'm interested in comparing anterior and posterior pieces of a tract generated 
by TRACULA. Ideally, I'd like to take the probabilistic map (i.e. the 
path.pd.nii.gz from one of the folders in SUBJECT/dpath) and obtain a 
"posterior part" and an "anterior part" by masking. Then I'd like to extract 
stats similar to the stats found in pathstats.overall.txt


Is this at all possible? I can produce the poster/anterior mask by hand for 
each individual subject, (although if there were an automated way to do this 
that I'm unaware of it would be great) but getting the stats out is something I 
can't quite figure out from the tutorials I've looked through.


Thanks for any help!
