Along-tract statistics for diffusion MRI tractography

Diffusion MRI tractography allows for the in vivo delineation of white matter tracts in the human brain in a manner that is individualized to the particular neuroanatomy of each person. Along-tract statistics is a set of tools for analyzing the scalar “quality” measures (FA, etc.) associated with these virtual dissections in a way that is parameterized along the curving axes of the tract spines, instead of the more typical method of averaging this variation into a single mean estimate for each tract.

This page is mainly here to collect video tutorials about these tools. The main source of documentation remains the Github Wiki.
