io.nibcompat¶
Module: io.nibcompat
¶
Compatibility functions for older versions of nibabel
Nibabel <= 1.3.0 do not have these attributes:
header
affine
dataobj
The equivalents for these older versions of nibabel are:
obj.get_header()
obj.get_affine()
obj._data
With old nibabel, getting unscaled data used read_img_data(img, prefer=”unscaled”). Newer nibabel should prefer the `get_unscaled method on the image proxy object
