VT-NAMIC Workflow Slicer-related issues

• Transforms loaded as .mat cannot be saved as .mat. Is there a loss of precision in transform shuffling?
• EM segmenter does not save some fields in the MRML
• extensions are not in Slicer path
• BRAINSFit version as of Oct 8 is broken -- need to revert to 301 that was used by AF earlier
• Slicer slider has inconsistent response to the clicks to the side of slider -- ignores clicks, then jumps -- very hard to do small adjustments
• See the directions matrix feature available in Slicer2 missing
• sometime when the transform is modified, it shows up as "Modified" in Slicer save dialog, but the checkbox is not set

Slicer-related, but not Slicer issues:

• N4ITK with the threaded bspline filter cannot handle tilted FOV volumes
• confirm N4ITK doesn't work with OrientedImage class
• BRAINSFit extension is totally broken as of Oct 9 svn
• investigate the cause of BRAINSFit failing in BSPline registration when mask is used and FOV tilted
