mne.export.export_epochs

mne.export.export_epochs(fname, epochs, fmt='auto', *, overwrite=False, verbose=None)[source]

Export Epochs to external formats.

Supported formats: EEGLAB (set, uses eeglabio)

Warning

Since we are exporting to external formats, there’s no guarantee that all the info will be preserved in the external format. See Notes for details.

Parameters
fnamestr

Name of the output file.

epochsinstance of Epochs

The epochs to export.

fmt‘auto’ | ‘eeglab’ | ‘edf’

Format of the export. Defaults to 'auto', which will infer the format from the filename extension. See supported formats above for more information.

overwritebool

If True (default False), overwrite the destination file if it exists.

New in version 0.24.1.

verbosebool | str | int | None

Control verbosity of the logging output. If None, use the default verbosity level. See the logging documentation and mne.verbose() for details. Should only be passed as a keyword argument.

Notes

New in version 0.24.

Export to external format may not preserve all the information from the instance. To save in native MNE format (.fif) without information loss, use mne.Epochs.save() instead. Export does not apply projector(s). Unapplied projector(s) will be lost. Consider applying projector(s) before exporting with mne.Epochs.apply_proj().

For EEGLAB exports, channel locations are expanded to full EEGLAB format. For more details see eeglabio.utils.cart_to_eeglab().
