GNU GPL v2 Yes NITRC hMRI-toolbox The hMRI-toolbox is an easy-to-use open-source and flexible tool, for qMRI data handling and processing. It allows the estimation of high-quality multi-parameter qMRI maps (longitudinal and effective transverse relaxation rates R1 and R2*, proton density PD and magnetisation transfer MT saturation), followed by spatial registration in common space for statistical analysis. hMRI-toolbox GNU GPL v2, MR http://www.nitrc.org/projects/hmri-toolbox/, http://www.nitrc.org/projects/hmri-toolbox/
