NIRAL Utilities

What is it?

NIRAL Utilities are open-source applications developped at UNC-Chapel Hill in the Neuro Image Research and Analysis Lab (NIRAL). These utilities are C++ based command line applications that allow image analysis and processing using ITK or VTK libraries.

Specifically the following utilities are contained thus far:

3DTo4DImages                - Converts 3D-vector images to 4D images

4DTo3DImages                - Converts 4D images to 4D-vector images

CombineDWIs                 - Combines multiple Diffusion Weighted Image (DWI) files into one file.

convertITKformats           - convert 3D images in all ITK formats (NRRD, NIFTI, GIPL, Meta etc)

CropTools                   - crops 3D and 4D images

DWI_NiftiNrrdConversion     - convert DWI and DTI from/to NRRD and NIFTI, works with UNC DTI tools and FSL

ImageMath                   - the swiss army knife image modification

ImageNoise                  - Computes Signal to Noise Ratio (SNR) or Contrast to Noise Ratio (CNR)

ImageStat                   - compute stats on images

IntensityRescaler           - rescale/normalize intensities using a prior brain tissue segmentation

ITKTransformTools           - Swiss army knife tool to handle ITK transform files

MauerDistanceTransform      - Calculates the Euclidean distance transform of a binary image

MultiAtlasSeg               - Segmentation with a Multi-Atlas strategy

NormalizeDWIGradientVectors - Normalizes Diffusion Weighted Image gradient vectors

PolyDataCompression         - Reads and writes polydata (*.vtk or *.vtp) to save them as
                              binary data as well as activates the compression of the file.

PolydataMerge               - Merges VTK polydata files

PolydataTransform           - Transforms polydata files

ReadImageHeader             - Prints the header of an ITK image (equivalent of 'unu head' but for
                              any image file format that ITK reads)

TransformDeformationField   - concatenates or average deformation fields (H-fields or displacement fields)

Software in Unsupported directory is not build with the main CMakeLists.txt file. It has to be build manually.
