Bug fixes targeted for this release

Sonia's reports on the DTI modules of the current Slicer4 release:

• Mantis Bug Reports:
  • Brain Mask (assigned to Demian, checked it out. It seems that it is a limitation of the Otsu strategy in this case due to the lack of padding, probably we need a real brain extraction tool)
  • Color by Orientation (assigned to Demian fixed)
  • Glyphs Visualization (assigned to Alex. fixed)
  • Fiducials Seeding (assigned to Alex. fixed )
  • Consistency of the GUI in the labelmap and fiducial seeding modules (assigned to Alex, fixed)
  • Scalar Measurement computation issue (Planar measure) : wrong window and level values in the Volumes module ( assigned to Julien Finet) is due to extreme values in the data - can this be clamped in the scalar estimation module? (assigned to Demian, fixed)
  • Scalar measurement update issue (fixed by Julien Finet)
  • DTI pipeline Windows 32 crash (Marianna's test: Mantis bug report xxx]
  • Scene Restore Issue in Slicer4 (assigned to: Jim)
• Suggested Reorganization of the Diffusion menu (assigned to Demian, Done)
  • Diffusion Data Conversion:
    • DICOM to Nrrd
    • DTIimport/export
  • DWI:
    • Brain Mask
    • Tensor Estimation
    • Denoising
  • DTI
    • Scalar Measurements
    • Tractography
    • Resample

• 'DicomToNrrdConverter' should be 'DICOM To NRRD Converter', and make the parameters of the Output sections visible on the GUI (assigned to Demian)

• Use new Slicer4 QTtesting functionalities for cross-platform Tests of Iowa Workshop tutorials (Benjamin/Sonia)

• Editor memory leaks and performance issues (Steve)

Deferred to after 4.1 freeze

• Fix for texture resolution: Alex
  • From Ron: for IGT need minimum 12Hz frame rate, maximum 200ms latency, preferred 30 hz frame rate and less than 100ms latency
• Update screenshot to reflect all possible layouts bug 1662 - Nicole
• storage nodes - Nicole

• Is it realistic to try for SimpleITK in this release? (After discussion: no, needs more testing - aim for summer project week)
  • Yes, if somebody can help with ITK 4 on windows.
  • linux packaging issue:
    • (2) itkXXX.so files are missing in the Slicer package.
  • linux discovering CLI:
    • (1) missing symbol on exit of CLI; in addition with a Qt bug, it fails to parse the CLI XML description
  • possibly other issues on window (needs testing)
    • (3) Building SWIG for SimpleITK is the problem.
  • need to try all the packaging platforms
    • packaging has never been tried on mac (J2 didn't try to compile on Mac neither)
    • packaging has never been tried on windows (because it doesn't compile)
