local_symmetry¶
A file that will be evaluated (in python) as a tuple of operators. Each operator is a tuple of name (str), rotation (tuple) and translation (tuple of 3 Angstrom floats). The rotation is the matrix specified as three row-tuples, each as a tuple of 3 floats). The unit operator is implied and therefore optional. The example below specifies two additional symmetry equivalents:
( ("p", (
(0.500000, 0.809000, -0.309000),
(-0.809000, 0.309000, -0.500000),
(-0.309000, 0.500000, 0.809000)
),
(0.000000, 0.000000, 0.000000)),
("e", (
(0.309000, -0.500000, 0.809000),
(0.500000, 0.809000, 0.309000),
(-0.809000, 0.309000, 0.500000)
),
(0.000000, 0.000000, 0.000000)))
