brainrise.transform.gaussian_random_field(shape, alpha=3.0, normalize=True, seed=None)[source]¶

Generates 3D gaussian random maps. The probability distribution of each variable follows a Normal distribution.

Parameters

shape : uplet,

the shape of the output Gaussian random fields.

alpha : flaot, default 3

the power of the power-law momentum distribution.

normalize : bool, default True

normalizes the Gaussian field to have an average of 0.0 and a standard deviation of 1.0.

seed : int, default None

seed to control random number generator.

Returns

gfield : array

the gaussian random field.
