White Matter Laterality/Asymmetry Measurement

Key Investigators

• Harvard Medical School: Lauren O'Donnell

Objective

1. Fast computation of white matter

   fiber tract laterality indices

   in python and ... Slicer4

Approach, Plan

1. So far have preliminary code running in python/vtk

   Slicer-ification is goal for this week

   Another goal: learn how to make an extension module

   Another goal: can this module use testing framework
