FBA and behavior

Hi there,

I completed the FBA analysis tutorial and created a group template (using the FBA tutorial here.

I would like to perform an analysis where I relate tracts between ROIs to specific behaviors. I have done this with traditional measures such as FA, MD, and RD. Is there a way to do this using a Fixel based analysis?


You might instead want to look at SIFT2 weights if you are looking at at bundles (as opposed to fixel-level). See here (Smith et al., 2022; Aperture Neruo): https://www.humanbrainmapping.org/files/Aperture%20Neuro/Accepted%20Works%20PDF/10_1015_Smith_Quantitative_streamlines_tractography.pdf
