Objective
We will extend the command line interface (CLI) to support more robust/generic communication between SLICER and third party modules. The primary object is to enable cross-compatibility between the MIPAV/JIST module framework and the SLICER CLI framework. Successful completion of this task would enable the Johns Hopkins CRUISE (cortical surface) and CATNAP (diffusion tensor imaging) modules to be run within SLICER. The secondary (and long term) objective is to establish a flexible and usable syntax for module/plugin communication with graphical front-ends which could be reused in other medical image analysis settings.
Approach, Plan
The XML syntax and parser implementation for the SLICER command line interface (CLI) will be studied. Recommendations will be made for extended (backward compatible) syntax. A prototype parser for the new schema will be implemented within SLICER.
Progress
- Surveyed existing CLI interface and identified areas for extension
- Implemented prototype JIST/MIPAV->CLI bridge and discovery procedure.
- Circulated drafts of revised "meta-protocol" layer for adaptation between existing CLI
- Communicated with XIP team about generating a common/compatible interface layer
See detailed results below.
Results
Areas for Investigation with CLI and Existing Limitations
- Multiple “programs” per executable.
- De-couple dependence of executable query (program which is called with “—xml") from the executable which implements desired functionality.
- Provide a mechanism to report non-resource (file-base) results, such as integer, vectors, etc.
- Report to both stdout (via xml markup) [optional]
- Generalize the calling syntax --- especially the ability to control argument structure.
- Allow authors to provide more meta-information about the algorithm (which may be ignored).
- Enable the concept of an “ignorable” parameter which need not be understood to use the program.
- Increase structure for information that authors can provide about their algorithms and moved this to a separate category.
- Increase documentation for “type-of” arguments. Attempted to provide more clarity on a “data-centric” view of the data rather than how these would be represented in ITK/VTK.
- Provide preferred and supported format syntax for resource (file) based communication.
- Ability to model dependencies between flags
- Workflow level perspective – “sample a bunch of points” = harness level things
- Ability to have variable number of output arguments and determine the number / names at RUNTIME

- These features will be released in the next version of JIST.
Framework for Interoperability of Neuroimaging Software
- Existing Slicer CLI can be bridge to almost any command line system through use of shell scripts.
- These scripts are platform specific and are complex to extend for larger projects --- do we write script factories? Factories for platform specific factories?
- If we are going to address the problem of inter-communication, perhaps it would be best to develop a SIMPLE architecture agnostic XML syntax for functionality query, programmatic direction, and result response.
- Started a NITRC project (FOPA - Framework for Open Programmatic Access) to develop multi-platform reference implementations. http://www.nitrc.org/projects/fopa/
