This app will fit the Neurite Orientation Dispersion and Density Imaging (NODDI; Zhang et al, 2012) model to multi-shell, normalized DWI data using the Accelerated Microstructure Imaging via Convex Optimization (AMICO; Daducci et al, 2015) toolbox. Requires normalized, multi-shell DWI data (including bvals and bvecs) and an optional brainmask of the DWI. Will output the four NODDI output files: neurite density index (ndi), orientation dispersion index (odi), isotropic volume fraction (isovf), and the directions (dirs).
