I generated the FD, FC, and FDC images using multi-tissue CSD according to the pipeline. https://mrtrix.readthedocs.io/en/3.0.2/fixel_based_analysis/mt_fibre_density_cross-section.html
However, I would like to transform the data from template space to subject space, so I can compare the results with other images using VOIs in subject space. Therefore, in step 10, I added the -nl_warp_full option to get the full warping.
Now, I tried the following commands, but sadly without success:
• mrtransform –warp_full Subj001_1_full_warp_FOD.mih -template …/template/wmfod_template.nii –from 2 Subj001_1_FD.nii Subj001_1_FD_native.nii
• mrtransform –warp_full Subj001_1_full_warp_FOD.mih -template …/template/wmfod_template.nii –inverse Subj001_1_FD.nii Subj001_1_FD_native.nii
Does anyone has some suggestions what I am doing wrong here?
