Hello,
I was wondering if anyone here has run analyses using tracula’s “along-the-tract” measures before?
I am hoping to perform groupwise comparisons along all 18 tracts tracula reconstructs, however I wish to have a better understanding of where each point provided maps to in MNI space. I am also concerned about potential multiple comparison issues.
I was wondering if anyone had advice on:
-
Whether points along the tracts should be examined individually or if they can be grouped meaningfully together?
- E.g. separating points along the ILF into posterior, medial, and anterior segments
-
If the former option in 1) is preferred (i.e. not grouping points together), are there some preferred options for comparison corrections beyond the standard bonferonni/fdr correction methods?
Thank you for any clarification/help given!
