Hi!

I have downloaded the brainnetome atlas BN_Atlas_246_1mm.nii.gz to use as the parcellation for my DTI processing. How can I convert this NIFTI parcellation into subject DTI space? Previously, I have used fat_proc_map_dti to bring FreeSurfer outputs into DTI space, but this .nii.gz file is not a FreeSurfer output and it is not in the subject's space already, so I don't know how fat_proc_map_dti would know the correct transformation. I have also created the FreeSurfer .annot files in fsaverage space for the Brainnetome atlas by following the instructions in BN_Atlas_freesurfer.zip. I can convert this to subject space using mri_surf2surf and then bring these surfaces into DTI space using fat_proc_map_dti, but then I have to inflate the parcels from the surface into the volume. If I am able to, it would make more sense for me to use the parcels in the volume that have already been created by the brainnetome group.

Thanks in advance for your help!
