Instructions:

  1. Create two separate coronal seed regions (at approx. coronal slice 75), one for each side.

  1. Create one ROA region and draw a sagittal ROA at the midline
  1. In the region list, check only the left seed/ROI region, then run fiber tracking. Based on this output, ROA placement will be clearer.
  1. Using the same ROA file, draw two more regions:
      1. on a coronal slice posterior to the seed regions
      2. on an axial slice inferior to the seed regions
  1. In the region list, 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.

    How do I pick my ROA’s? Where is this pathway supposed to go? Supposed to end?

  2. Kurt says:

    Having a seed and ROI so close to each other seems redundant. Once this pathway is better described, a more intuitive placement of 2 ROIs seems necessary.
