TBSS Non-FA Image Projection¶
Library: FSL | Docker Image: brainlife/fsl
Function¶
Projects non-FA diffusion images (MD, AD, RD, etc.) onto the mean FA skeleton using the same registration from the FA-based TBSS pipeline.
Modality: Non-FA diffusion scalar maps (3D NIfTI) in same space as FA images used for TBSS.
Typical Use: Analyzing MD, AD, RD, or other diffusion metrics on the FA-derived skeleton.
Key Parameters¶
Key Points¶
Must run full TBSS pipeline on FA first. Non-FA images must be in same native space as original FA. Creates all_
