Hi Qianwen – You don’t have to do (1) and (2), trac-all –stat does that for you. For a description of the measures, see the tutorial: http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/TraculaStatistics and the course slides: http://surfer.nmr.mgh.harvard.edu/pub/docs/tracula,fs.ppt

Dear experts, I have some questions about along-path analysis: (1)how to determine the first position and last position of all subjects' pathway when converting all pathstats.byvoxel.txt files to a table for group analyses?
(2)how to complete correspondence of points between subjects?
(3)what is values in table for group analyses,diffusion measure of center or something else?
Thanks! Qianwen
