Numpy array to nifti

WebNifti allows the header to be a separate file, as part of a nifti image / header pair, or to precede the data in a single file. The object needs to know which type it is, in order to manage the voxel offset pointing to the data, extension reading, and writing the correct magic string. This class handles the header-preceding-data case. Web14 aug. 2024 · Nibabel is a library designed specifically for nifti extensions, but the conversion array/nifti requires a numpy array as input.
