I conducted a whole-brain Fixel-Based Analysis (FBA) and also performed Voxel-Based Analysis (VBA) using FA images. For the VBA part, I used SPM’s TFCE tool to perform statistical analysis and obtained the corresponding results.
My goal is to identify ROIs between the two analysis methods.
The approach I used is as follows:
I overlaid the TractSeg bundle segmentations onto the wmfod_template.mif, and by inputting the coordinate values (x, y, z) from the TFCE results, I examined whether those coordinates overlap with any of the TractSeg masks.
Below is a summary table of the findings. I would greatly appreciate any suggestions or feedback from the experts.
Thanks.
Best wishes,
Vivian
