Warping functional ROIs from MNI space to wmFOD template space

Hi MRtrix Community, I write for a suggestion on the best steps to ‘move’ (or warp) functional ROIs (6mm sphere) from the MNI to the FOD template space. These ROIs were obtained with a functional localizer (fMRI) and will be the seeds to generate ‘tracks of interest’ from a whole-brain sift track file. This issue was partially covered in a couple of old posts, but the poor description of the steps made me even more confused (sorry! :S). My general understanding is: [ ] Take the first volume…

Registration of structural and diffusion weighted data

Just a comment. Updated some old scripts that uses FLIRT for registration for this purpose. So the ref image is the highres structural image and moving image a suitable dwi image. Now with transformconvert you don’t have to bother with flipping dims for the subsequent mrtransform So in principle it works like this: flirt -in mov_brain.nii.gz -ref ref_brain.nii.gz -dof 6 -omat mov2ref.mat transformconvert mov2ref.mat mov_brain.nii.gz ref_brain.nii.gz flirt_import mov2ref_mrtrix.txt mrtransfo…
