Hi Andrade, I'm adding the FreeSurfer support list so other can benefit.
To answer your question, you would use the first dicom from the diffusion scan... but since you don't have the dicoms that won't work. You can combine all of the DTI nifty files into one multi-frame diffusion 4d volume using mri_concat. mri_concat /path/to/all/IXI025-Guys-0852-DTI-??.nii.gz --o /output/path/dti.mgz Then run dt_recon using dti.mgz as your input. cd /path/to/desired/subjects/dir export SUBJECTS_DIR=$(pwd) dt_recon --b /path/to/bvals.txt /path/to/bvecs.txt--i /path/to/dti.mgz --s andrade --o /path/to/desired/diffusion/output Let me know if this works.

I don't have a dicom format file for dtrecons. What I have is nii.gz all that I gave you. In case I need to do dcmunpack either way I need to do dtrecons for each of those dcmunpack or just the first one?
