How can i map DTI data to CIFTI space ?
Is it available to map non-HCP DTI data to CIFTI ?
As for a diffusion pipeline. It depends on the use case.
- If you want to study diffusion based properties of gray matter (i.e. NODDI) on the cortex in cifti format. I would recommend using "myelin-style" volume to surface mapping.
- Another (more common) use would be to define gray matter ROIs for tractography. To do this, you should use wb_command -label-to-volume-mapping (for atlases) or wb_command -metric-to-volume (for weighted masks) to convert the cifti masks back into that particular participants nifti T1w space.
I can send some example code depending on the use case.

Hello Dr. Dickie,
I am interested in the first scenario you mention above - projecting diffusion metrics (MD and NODDI metrics) to the cortex for further analysis. Do you recommend myelin-style mapping vs ribbon-constrained to help account for partial voluming? If you have any example code for this use case, it would be much appreciated. Thanks!

Hi Jeremy,
I am also trying to project NODDI metrics to the cortex for further analysis. I'm wondering if you figured this out/have any examples you could share?
It would be much appreciated!
Thanks,
Maya
