dMRI-Lab: advanced diffusion MRI with Matlab
This is a Work-In-Process toolbox designed for Matlab(R) and aimed at the computational analysis of diffusion MRI. It addresses basic concepts such as Diffusion Tensor Imaging (DTI), but also advanced topics like High Angular Resolution Diffusion Imaging (HARDI, including estimation and representation of Orientation Distribution Functions-ODF), multi-shell samplings, and computational diffusion MRI. We have tested the library for Matlab versions starting R2015b, but we advice using a more recent version. A working license for the Parallel Computing Toolbox is strongly recommended (but not necessary).
- Download the package and unzip to a local folder at will.
- From the Matlab command window, cd to the home folder, i. e. that containing the setup script "setup__DMRIMatlab_toolbox.m".
- Run the setup script as either:
- >> setup__DMRIMatlab_toolbox('useparallel',true);
- >> setup__DMRIMatlab_toolbox('useparallel',false); or simply: >> setup__DMRIMatlab_toolbox;
for using/avoid using the Parallel Computing Toolbox. In case you don't have a working license for it, the script will not throw an error. This will setup your Matlab path for the present session (it won't make any permanent change).
- Open/run some of the demo files in the "examples" folder to get started.
