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.
