Imaging sessions on 30 healthy subjects. Imaging modalities include T1, DTI, HARDI and working memory fMRI. All data have been converted to NIFTI format. This is intended to be a resource for statisticians and imaging scientists to be able to quantify the reproducibility of gray matter surface based spatial statistics.
