mne.compute_proj_epochs¶

mne.compute_proj_epochs(epochs, n_grad=2, n_mag=2, n_eeg=2, n_jobs=1, desc_prefix=None, verbose=None)[source]¶

Compute SSP (spatial space projection) vectors on Epochs.

Parameters:

Parameters:	epochs : instance of Epochs The epochs containing the artifact n_grad : int Number of vectors for gradiometers n_mag : int Number of vectors for magnetometers n_eeg : int Number of vectors for EEG channels n_jobs : int Number of jobs to use to compute covariance desc_prefix : str \| None The description prefix to use. If None, one will be created based on the event_id, tmin, and tmax. verbose : bool, str, int, or None If not None, override default verbose level (see `mne.verbose()` and Logging documentation for more).
Returns:	projs: list List of projection vectors
