Project Description

Objective Approach and Plan Progress and Next Steps
  • Explore how Slicer can interact with an existing web-based, open-source workflow system (Flow, developed by Kitware and KnowledgeVis, LLC)
  • Exchange data between 3D Slicer and the Flow workflow system
  • Load a MRML scene into Slicer and read images into Flow by accessing through Slicer's RestAPI
  • Use Steve's (work in progress) SlicerWeb Extension to respond to REST requests from Flow
  • Connect with Girder-breakout team to discuss data sharing between systems (Slicer, Girder, Flow, etc.)
  • (after project week), expand to work for whole NRRD image that comes from the REST API.
  • Hosted Slicer locally and was able to reach the REST API, extracting
  • Retrieved a 2D Slice from Slicer and automatically ran it through a small workflow
  • Next step would be to retrieve named volumes as 3D NRRD format from the SlicerWeb
  • Productive discussions were conducted with the NiPype team regarding how to utilize the Flow engine as an interface for NiPype-executed computation
