eegprep.eeg_interp(EEG, bad_chans, method='spherical', t_range=None, params=None, dtype='float32')#

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 interpolation computation. Use "float32" to match MATLAB-oriented workflows with lower memory use, or "float64" for full precision.
