Regarding: TBSS tbss_1_preproc

Hi everyone.
During the running the tbss_1_preproc script, how to (create FA data from a diffusion MRI study) in TBSS part First. How to execute?

Hi Ali,

If you are intended to create your FA maps with FSL, you can follow their guides: FDT/UserGuide - FslWiki

Otherwise, if you are intended to create FA maps and preprocessing with MRtrix, you can simply follow the preprocessing pipeline DWI denoising — MRtrix 3.0 documentation, Gibbs ringing artifact removal, and DWI distortion correction using dwifslpreproc — MRtrix 3.0 documentation. Then, you can generate brain FA masks following dwi2mask, dwi2tensor and tensor2metric (with -fa flag).

Hope this helps.
