eeg_interp

eeg_interp(EEG, bad_chans, method='spherical', t_range=None, params=None, dtype=None)

Interpolate missing or bad EEG channels using spherical spline.

interpolation.

Parameters

EEGdict

EEG data structure with ‘data’, ‘chanlocs’, ‘nbchan’, etc.

bad_chanslist, array-like, or list of dicts

Channel names, channel indices, or channel-location dictionaries. When channel-location dictionaries are provided, the function can return unchanged data for identical locations, append new channels when no existing locations overlap, or remap data when existing channels are a subset of the requested channel structure.

methodstr, optional

Interpolation method (‘spherical’, ‘sphericalKang’, ‘sphericalCRD’, ‘sphericalfast’, ‘invdist’/’v4’, or ‘spacetime’).

t_rangetuple, optional

Time range for interpolation

paramstuple, optional

Method-specific parameters

dtypestr or dtype, optional

Precision for the spherical-spline computation. The default follows the floating-point dtype of EEG['data'], and uses float64 when the data are not floating point. Pass "float32" for the lower-memory path.

Returns

EEGdict

Updated EEG structure with interpolated channels
