mne.read_cov

mne.read_cov(fname, verbose=None)

Read a noise covariance from a FIF file.

Parameters

fnamestr

The name of file containing the covariance matrix. It should end with -cov.fif or -cov.fif.gz.

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.

Returns

covCovariance

The noise covariance matrix.
