[Na-mic-project-week] Introducing two projects to discuss for NA-MIC week

[Andras Lasso]

Matlab integration:

All Matlab commands are executed in the same session. All variables (except local variables that you define in a function) are preserved, unless you specifically request closing of Matlab after command execution.

You can directly enter commands and see results using MatlabCommander module. We can add a Python utility function that can send a command to Matlab using MatlabCommander and print the result on the Python console. Something like:
>> matlab(‘a=5*5’)
ans=25

We can also implement support for table nodes on the MatlabBridge interface. It could allow sending/receiving parameters bypassing the GUI generated by the CLI XML description (I’m not sure how useful it is but it is easy to do).

Subject: Introducing two projects to discuss for NA-MIC week

Hi everyone,

I wanted to introduce you to two topics I would like to investigate and discuss during the next conference call and the na-mic week in Boston:

Volumetric Mesh support:
We collaborate on a project which uses finite element meshes to compute light propagation within soft tissues for optical imaging. Their mesh is computed using label map images, and they would like to visualize their output data overlayed above the structural images used for the segmentation without having to resample it within the original volume domain. JC directed me to the interesting work that is still in Slicer 3.6<https://www.slicer.org/wiki/Modules:IA_FEMesh-Documentation-3.6>. The discussion on this topic could be related to the potential wrapping of VTK unstructured grid, to think about where it could fall within the current nodes hierarchy (link with models...), etc...

MatLab tighter integration:
Right now - based on my current understanding of the framework - MatLabBridge allows us to forward commands to a MatLab server and retrieve information, and offers methods to convert data to and from MatLab, but the workspace environment instanciated while processing the given commands is lost (no way to still access the MatLab variables created, to keep using MatLab from the latest state). We would like to investigate a solution that would allow us to keep the MatLab state alive, to visualize the MatLab workspace variables within Slicer (table node?), to directly enter MatLab commands within Slicer (using a custom ctkConsole, like the python console?)

Looking forward to hearing your thoughts and possible interests in those topics.

Best regards,
