2011 Winter Project Week:Command line module logic redesign

• 

  Projects List

• 

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
