nilearn.image.new_img_like¶

nilearn.image.new_img_like(ref_niimg, data, affine=None, copy_header=False)[source]¶

Create a new image of the same class as the reference image.

Parameters:

ref_niimgNiimg-like object or SurfaceImage

Reference image. The new image will be of the same type.

datanumpy.ndarray, PolyData, or dict of numpy.ndarray, str, pathlib.Path

Data to be stored in the image. If data dtype is a boolean, then data is cast to ‘uint8’ by default.

Changed in version 0.9.2: Changed default dtype casting of booleans from ‘int8’ to ‘uint8’.

If ref_niimg is a Niimg-like object, then data must be a numpy.ndarray.

affine4x4 numpy.ndarray, default=None

Transformation matrix. Ignored for SurfaceImage.

copy_headerbool, default=False

Indicated if the header of the reference image should be used to create the new image. Ignored for SurfaceImage.

Returns:

Niimg-like or SurfaceImage object: A loaded image with the same file type (and, optionally, header) as the reference image.
