TBSS Step 3: Post-Registration¶
Library: FSL | Docker Image: brainlife/fsl
Function¶
Creates mean FA image and FA skeleton by projecting registered FA data onto a mean tract center.
Modality: Registered FA images from tbss_2_reg.
Typical Use: Third step of TBSS: creating the white matter skeleton for analysis.
Key Parameters¶
-S (use study-specific mean FA and skeleton), -T (use FMRIB58_FA mean and skeleton)
Key Points¶
Creates mean_FA, mean_FA_skeleton, and all_FA (4D). Skeleton threshold typically 0.2 FA. -S recommended for study-specific analysis.
