NiftyReg: 390df2baaf809a625ed5afe0dbc81ca6a3f7c647
For the SSM plugin, you will need VTK 5.8.0. To get a updated version of VTK 5.8.0, see my [VTK 5 related blog post](http://l3mmings.blogspot.com.au/2015/06/vtk-5-and-ffmpeg-shenanigans-on-windows.html). VTK 5.10.1 will also work for the SSM plugin, but is known to have image display bugs.

Important Notes about Dependencies and OSes:
VTK 5.10.1 and VTK 7.0.0 will also work, but is known to have image display bugs.
Mac OSX support is limited because of availability of machines to the developer and restrictive Apple EULAs. Builds and plugins work correctly on local builds. DMG installers have issues with plugins at the moment.

Installers/Binaries Notes:
The -SSM designation points to installers with the shape model plugin. See [YouTube video](https://www.youtube.com/watch?v=j95C1Y3swfw&t=2s) showing this feature.
The USB key installer is for those who have issues with installers or don't like installers or need portable running versions of SMILI. These also provide shared libraries for development.

Other binaries and installers for other OSes will be added over time.
