Home < Linear Mixed-effects shape model to explore Huntington's Disease Data

Key Investigators

  • UIowa: Hans Johnson, Dave Welch
  • Utah: Manasi Datar, Josh Cates, Ross Whitaker

Objective

Make the linear mixed-effects shape model accessible for further exploration of Huntington's Disease Data

Approach, Plan

Meet with UIowa team to:

  • give an overview of results from the linear mixed-effects shape model
  • explain the ShapeWorks command line tools to optimze and analyze correspondences
  • discuss next steps toward making these tools accessible to UIowa team, to facilitate further exploration of the Huntington's disease Data

Progress

  • preliminary results look promising
  • ITKv4 module for mixed-effects model (Josh) available for Manasi to test
    • ITKv4 module tested on Linux system
    • Mixed-effects model for shapes from a single structure from the HD data (in progress)
  • Once tested, this module can be used by UIowa team on a larger cohort of cases
