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 | None

Control verbosity of the logging output. If None, use the default verbosity level. See the logging documentation and mne.verbose() for details. Should only be passed as a keyword argument.

Returns:

covCovariance

The noise covariance matrix.
