mne.preprocessing.interpolate_bridged_electrodes

mne.preprocessing.interpolate_bridged_electrodes(inst, bridged_idx, bad_limit=4)

Interpolate bridged electrode pairs.

Because bridged electrodes contain brain signal, it’s just that the signal is spatially smeared between the two electrodes, we can make a virtual channel midway between the bridged pairs and use that to aid in interpolation rather than completely discarding the data from the two channels.

Parameters

instinstance of Epochs, Evoked, or Raw

The data object with channels that are to be interpolated.

bridged_idxlist of tuple

The indices of channels marked as bridged with each bridged pair stored as a tuple.

bad_limitint

The maximum number of electrodes that can be bridged together (included) and interpolated. Above this number, an error will be raised.

New in v1.2.

Returns

instinstance of Epochs, Evoked, or Raw

The modified data object.
