nilearn.image.load_img¶

nilearn.image.load_img(img, wildcards=True, dtype=None)[source]¶

Load a Niimg-like object from filenames or list of filenames.

Added in version 0.2.5.

Parameters:

imgNiimg-like object: If string, consider it as a path to NIfTI image and call nibabel.load()`on it. The ‘~’ symbol is expanded to the user home folder. If it is an object, check if affine attribute is present, raise `TypeError otherwise. See Input and output: neuroimaging data representation.
wildcardsbool, default=True: Use img as a regular expression to get a list of matching input filenames. If multiple files match, the returned list is sorted using an ascending order. If no file matches the regular expression, a ValueError exception is raised.
dtype{dtype, “auto”}, optional: Data type toward which the data should be converted. If “auto”, the data will be converted to int32 if dtype is discrete and float32 if it is continuous.

Returns:

3D/4D Niimg-like object: Result can be Nifti1Image or the input, as-is. It is guaranteed that the returned object has an affine attributes and that nilearn.image.get_data returns its data.
