   * \brief This plugin provides an extension for Tract-based spatial statistics (see Smith et al., 2009. http://dx.doi.org/10.1016/j.neuroimage.2006.02.024)
   * TBSS enables analyzing the brain by a pipeline of registration, skeletonization, and projection that results in a white matter skeleton
   * for all subjects that are analyzed statistically. This plugin provides functionality to select single tracts and analyze them seperately.
