Extension Description

DTIProcess is a DTI processing and analysis toolkit developed in UNC and University of Utah. Tools in this toolkit include:

• dtiestim: tool that takes in a set of DWIs in nrrd format and estimates a tensor field out of it. It also has many useful options.
• dtiprocess: tool that handles tensor fields
• maxcurvature: computes Hessian of an image. Typically the input image is a Fractional Anisotropy (FA) image
• dtiaverage (Should be used in a command line): program that allows to compute the average of an arbitrary number of tensor fields
• fibertrack: program that implements a simple streamline tractography method based on the principal eigenvector of the tensor field
• fiberprocess: tool that manage fiber files extracted from the fibertrack tool or any fiber tracking algorithm
• fiberstats: program that prints out some statistics computed on a fiber bundle
• A couple other tools that are included in the package and that are not CLI compatible

All the above software will appear in 3D Slicer in the module list under Diffusion>NIRALPipeline
