Key Investigators

  • Isomics: Steve Pieper
  • GE: Jim Miller

Objective

Develop mechanisms for CommandLineModules to be

  • More interactive
    • return intermediate results
    • steerable
  • More autonomous
    • automatically execute with changes in MRML
  • High level task oriented
    • chain modules together into workflows

while maintaining the simple conceptual model of SEM.


Approach, Plan

  • Develop more communication channels between Slicer and a Command Line Module
  • Develop a MRML-Observer-SEM pattern
  • Use Python interface to call command line modules, script modules to chain
  • Develop a workflow to manage a chain of command line modules and their UI


Progress

Ideas:

  • Have GenerateCLP put parameters into an object
  • Have current variables be references to the object ivars
  • Have a mode in GenerateCLP to not generate the local variables, just the object of variables
  • Define standard API to report a change in a parameter value from harness to plugin and plugin to harness
    • Have GenerateCLP create a method called Update<ParameterName>?
      • Have generated code call user function when changed?
    • Entry points in shared object
    • Message in stdin/stdout for executables
