Project Description

Objective

• Share development code
  • Test on a few longidutidal data set
  • Identify any immediate improvement requirement
  • Identify long-term improvement requirement
  • Make sure the implementation is applicable on large-scale dataset.

• See differences of Shape analysis between current and old version of segmentation
  • Estimate time efficiency
  • Estimate what is improved
• Identify 6 month goals/plans for Shape Analysis Project

Approach, Plan

• Sharing code: github
• Testing: 8 subjects with longitudinal data has been identified.
  • Sampled from control(2), low(2), medium(2), and high(2) CAP group.
  • Also sampled from 6 different sites

Progress

Shape Analysis Pipeline Installation

Shape analysis pipeline requires installation of two main tools:

1. Deformetrica (James Fishbaugh)
2. ShapeWork (Prasanna Muralidharan)

Deformetrica (http://www.deformetrica.org) installation

1. Download 'Deformatrica 2.1' from http://www.deformetrica.org/?page_id=15
2. Go to "Installation Instructions" and follow the instructions

• FFT download & installation:
