The database can be requested from cyril.poupon@cea. fr and will be available from the Human Brain Project in a near future.  ...  The first attempt of clustering short association fibers was done by Guevara et al. (2012) , leading to the creation of an atlas of short association fibers of the left hemisphere.  ...  For the atlas creation, the robust atlas creation method uses two independent groups of subjects.  ...
