mne.simulation.add_noise¶

mne.simulation.add_noise(inst, cov, iir_filter=None, random_state=None, verbose=None)[source]¶

Create noise as a multivariate Gaussian.

The spatial covariance of the noise is given from the cov matrix.

Parameters

instinstance of Evoked, Epochs, or Raw: Instance to which to add noise.
covinstance of Covariance: The noise covariance.
iir_filterNone | array_like: IIR filter coefficients (denominator).
random_stateNone | int | instance of RandomState: If random_state is an int, it will be used as a seed for RandomState. If None, the seed will be obtained from the operating system (see RandomState for details). Default is None.
verbosebool, str, int, or None: If not None, override default verbose level (see mne.verbose() and Logging documentation for more). If used, it should be passed as a keyword-argument only.
