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 Nilearn 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.

dtypedtype like, “auto” or None, default=None

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. If None, data will not be converted to a new data type.

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.
