EMSegmenter in Slicer4

TODO

• untie KWWidgets from EMSegment base
• untie KWWidgets from EMSegment commandline tool
• create EMSegment4 as an extension for Slicer4
  • include the commandline tool in the extension (Problem: infrastructure is not ready yet)
• Merge old EMSegment4 and the new extension all in Slicer3 repository
• introduce Slicer Common Interface (SCI) which holds functionality which is different between Slicer3 and Slicer4 but provides the same API for both
  • provide EMSegment3 functionality in the SCI
  • provide EMSegment4 functionality in the SCI (work in progress)
• update EMSegment4 Qt Gui
• provide nightly extension builds

Slicer Common Interface (SCI)

The Slicer Common Interface is a class with a unified API for Slicer3 and Slicer4 which includes functionality which has to be realized differently among the two Slicer versions.

• Step3: Define anatomical tree
  • qt widget does not support creating subclasses yet
  • all done
• Step4: Define Atlas
  • qt widget supports parcellation maps
  • all done
• Step5: Edit Registration parameters
  • problem: show input channels-volume map does not work yet
  • all done

Open issues reported by Kilian

• "Attempt to go to the finish step succeeded" message when clicking segment
  • this is a ctk error
• step 3: reduce size of probability map fields (not possible)
• step 7: "Plot distribution" functionality
• step 7: incorrect mean in manual sampling mode (found the cause I think)
• step 7: incorrect reset of distribution
• step 7: size of anatomical tree not optimal
• step 7: remove auto-sampling
• step 9: grey out forward button
• put emsegmenter in category segmentation
• all steps: tooltips
• order task list alphabetically
