Instructions:

  1. Create two separate axial seed regions (at approx. axial slice 87), one for each side.

  1. Create one ROA region and draw a sagittal ROA slice at the midline
  1. In the region list, check only the left seed region, then run fiber tracking. Based on this output, ROA placement will be clearer.
  1. Using the ROA region, draw four more ROA regions
      1. on a coronal slice posterior to the seed region
      2. on a coronal slice anterior to the seed region
      3. on a sagittal slice lateral to the left seed region
      4. on a sagittal slice lateral to the right seed region.
  1. Create one term region on an axial slice inferior to the seed region, at the base of the cerebellum.
  1. Check only the left seed region and ROA regions, then perform fiber tracking. Under the tract list, make sure only the desired left tract is checked and highlighted in purple. Save region, tract, and density files.
  1. Uncheck the left seed region and check the right seed region and ROA region, then perform fiber tracking. Make sure only the desired right tract is checked and highlighted in purple. Save region, tract, and density files.

    Where are ROA’s drawn? They should reference anatomy in some way instead of arbitrarily anterior/posterior to seed.
