Dataset loading its samples from a NIfTI image or file. Samples can be loaded from a NiftiImage instance or directly from a NIfTI file. This class stores all relevant information from the NIfTI file header and provides information about the metrics and neighborhood information of all voxels. Most importantly it allows to map data back into the original data space and format via :meth:`~mvpa.datasets.nifti.NiftiDataset.map2Nifti`. This class allows for convenient pre-selection of features by providing a mask to the constructor. Only non-zero elements from this mask will be considered as features. NIfTI files are accessed via PyNIfTI. See http://niftilib.sourceforge.net/pynifti/ for more information about pynifti.
