Returns

mantidimaging.core.io.utility.find_projection_closest_to_180(projections: numpy.ndarray, projection_angles: numpy.ndarray) → Tuple[numpy.ndarray, float]

Finds the projection closest to 180 and returns it with the difference. :param projections: The array of projection images. :param projection_angles: The array of projection angles. :return: The 180 projection/the closest non-180 projection and the difference between its angle and 180.

mantidimaging.core.io.utility.get_candidate_file_extensions(ext: str) → List[str]

Gets a list of file extensions which can be used to load files. :param ext: User provided file extension :returns: List of extensions in the order they should be tested

>>> get_file_extension("/home/user/file_path.test")
'test'
>>> get_file_extension("/home/user/file.path.test")
'test'
>>> get_file_extension("/home/")

# above is expecting a None which.. well doesn’t show as anything so just # an empty line with a comment explaining it

Parameters

path – The path to be checked.

Returns

All the folder names, sorted by ascending
