mne.rename_channels(info, mapping, allow_duplicates=False, verbose=None)[source]

Rename channels.


The mne.Info object with information about the sensors and methods of measurement. Note: modified in place.

mappingdict | callable()

A dictionary mapping the old channel to a new channel name e.g. {‘EEG061’ : ‘EEG161’}. Can also be a callable function that takes and returns a string.

Changed in version 0.10.0: Support for a callable function.


If True (default False), allow duplicates, which will automatically be renamed with -N at the end.

New in version 0.22.0.

verbosebool | str | int | None

If not None, override default verbose level (see mne.verbose() and Logging documentation for more). If used, it should be passed as a keyword-argument only.
