mne.add_reference_channels¶

mne.add_reference_channels(inst, ref_channels, copy=True)[source]¶

Add reference channels to data that consists of all zeros.

Adds reference channels to data that were not included during recording. This is useful when you need to re-reference your data to different channel. These added channels will consist of all zeros.

Parameters:

Parameters:	inst : instance of Raw \| Epochs \| Evoked Instance of Raw or Epochs with EEG channels and reference channel(s). ref_channels : str \| list of str Name of the electrode(s) which served as the reference in the recording. If a name is provided, a corresponding channel is added and its data is set to 0. This is useful for later re-referencing. copy : bool Specifies whether the data will be copied (True) or modified in place (False). Defaults to True.
Returns:	inst : instance of Raw \| Epochs \| Evoked Data with added EEG reference channels.

inst : instance of Raw | Epochs | Evoked

Instance of Raw or Epochs with EEG channels and reference channel(s).

ref_channels : str | list of str

Name of the electrode(s) which served as the reference in the recording. If a name is provided, a corresponding channel is added and its data is set to 0. This is useful for later re-referencing.

copy : bool

Specifies whether the data will be copied (True) or modified in place (False). Defaults to True.

Returns:

inst : instance of Raw | Epochs | Evoked

Data with added EEG reference channels.
