> The latter is specified in the TBSS manual.

> The results of (1) is T-statistics at every location in the skelaton (which lines up with every part of the mean_FA_skelaton_mask), while the results of (2) are a very limited number of non-zero voxels within the mask. For the voxels that are non-zero, they are the same as (1).

> Am I applying the wrong mask or is the mask just being incorrectly used by the program for some reason? I'm very puzzled as to why I would get values of 0 inside the mask. The data are from monkeys, but that shouldn't effect the program, with a resolutions of .5x.5x2.5mm. Any thoughts would be appreciated.
