Technical:

1. What mesh input formats does this software work with?
   The program works on meshes in vtk PolyData format, or byu format. Other data formats can be read into CAWorks and written out as vtk PolyData for use with this program.
   
   
2. What kind of hardware, operating systems does the tool run on?
   This program currently runs on Ubuntu 12, and should run on any OS system that can compile the Insight Tool Kit.
   
   

General

1. How can I download the software?
   The code was submitted to its own branch of the ITK Gerrit Code review repository and is currently being reviewed. To get the current code run the following git commands:

   git clone git://itk.org/ITK.git
   cd ITK
   git fetch http://review.source.kitware.com/p/ITK refs/changes/53/7553/4 && git checkout FETCH_HEAD -b KernelPCAOnMeshes
   

   
   
   
2. How do I build the software?
   From the source directory create a build directory, then use cmake to configure the code and make to build it:

   mkdir ../build
   cd ../build
   cmake-gui ../ITK
   

   Click "Configure" for the initial configuration. Select your options. VectorKernelPCA is in Examples, so be sure to select BUILD_EXAMPLES and ITK_BUILD_ALL_MODULES. Click "Configure" until the "Generate" button is enabled. Click the "Generate" button. Exit cmake-gui and build the code

   make
   

   
   
3. How is the software being used currently?
   The Principal Component calculations are used at the front end of statistical pipelines CIS uses for computational anatomy. They will be used to produce basis functions on surfaces used in CIS shape analysis studies.
   
   
4. How do I use this tool on CIS resources?
   It is necessary to get an account on the CIS file system to use this software at this time. To get an account, please contact Anthony Kolasny (see the feedback section).
   
   The VectorKernelPCA program can be found at

   /cis/project/ncbc/src/pca/build/bin/VectorKernelPCA
   

   Read the manual for a description of the input parameters.
