Hands-On: Patients with spinocerebellar ataxia

Longitudinal comparison

  1. Download two scan session data of sub-SCA202 at the SCA2 Diffusion Tensor Imaging study
  2. Create two SRC files
  3. Construct FIB files
  4. Export NQA from the follow-up scan
  5. Open the FIB file of the baseline and load the NQA with registration.
  6. Differential fiber tracking to show the change.

Testing the Results

Practicum assignment: Cross-sectional comparison using Differential tractography

  1. Create a connectometry database using control data at the SCA2 Diffusion Tensor Imaging study
  2. Generate a subject-matched NQA map at [Step C2a: Modify a Connectometry Database]
    • Documentation
    • Subjects demographics: participants.tsv (need to be modified to keep only values)
  3. Open the baseline FIB file of the patient #2 and load the subject-matched NQA using [Slice][Insert MNI image]
  4. Differential fiber tracking to show the change.
