- 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 channels. These added channels will consist of all zeros.

str|listofstr 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.
- copybool
Specifies whether the data will be copied (True) or modified in-place (False). Defaults to True.

When re-referencing, make sure to apply the montage using
mne.io.Raw.set_montage()only after calling this function. Applying a montage will only set locations of channels that exist at the time it is applied.
