1.) Install the modified NiftyReg version, provided in the reg_stack download. Once extracted, NiftyReg source files will appear in the nifty_reg folder. Installation instructions can be found at http://cmictig.cs.ucl.ac.uk/wiki/index.php/NiftySeg_install, as well as further documentation. Note that for the GPU implementation, a CUDA capable GPU must be installed with appropriate drivers and CUDA SDK. Special consideration must be taken to enable GPU usage when building NiftyReg.
2.) The latest reg_stack Python script (e.g., reg_stack-1.0.py) will also be extracted. You must install Python 2.7.X along with the following packages:
-NumPy
-SciPy
-PyDICOM
-Python Imaging Library (or Pillow)
-nose
-sphinx
-NiBabel
