Hi all
I want to use a freesurfer parcellation as a seed point in DTI analysis using a non-FSL DTI tractography tool.
I have the raw DTI images for around 40 subjects (20 scz 20 controls). From the structural MPRAGEs that correspond to these subjects, I have an average image where I have my defined ROI (which is a freesurfer atlas based parcellation). The ROI has numerous vertices whose MNI coordinates are available to me.
Please correct me if I have understood this properly
  1. I have to process the raw DTI images to obtain FA/trace images first for each subject
  2. each FA/trace image should be registered to the average structural MPRAGE of the group
How do I then go on to obtain the coordinates for my label on the DTI space?

Many thanks
Lena
