Method Details [hide private]

__init__(self, samples=None, mask=None, dsattr=None, **kwargs)
(Constructor)

source code 
Initialize NiftiDataset.
Parameters:
  • samples - Filename (string) of a NIfTI image or a NiftiImage object
  • mask - Filename (string) of a NIfTI image or a NiftiImage object
Overrides: object.__init__

map2Nifti(self, data=None)

source code 
Maps a data vector into the dataspace and wraps it with a NiftiImage. The header data of this object is used to initialize the new NiftiImage.
Parameters:
  • data (ndarray) - The data to be wrapped into NiftiImage. If None (default), it would wrap samples of the current dataset

niftihdr

Value:
property(fget= lambda self: self._dsattr ['niftihdr'], doc= 'Access to\
 the NIfTI header dictionary.')
