Project Description

Objective

Work towards creating a Slicer4 extension for the white matter query language, originally developed by Demian Wassermann.

Approach, Plan

We currently have the WMQL as a python scripted module. We need to resolve several issues:

  • how to incorporate dependencies, such as numpy 1.7.
  • extend the user interface
  • create documentation
  • create Slicer 4 extension

Progress

  • The major technical hurdle that remains to be solved before creating a Slicer extension is the code's dependency on numpy 1.7. A long-term solution would be to update Slicer to work with numpy 1.7.
  • In the meantime, we have a working prototype for a Slicer module that works if numpy 1.7 is manually installed. The source code is available in a github repository: https://github.com/llcmgh/slicer_tract_querier
  • Overall view with initial full set of fiber tract and user interface:

  • Zoom-in on the user interface, with the window to enter the WMQL command:

  • Extracted fibers overlaid on initial full set of fibers:
