Dear Denis,

Thank you for your help. I have another simple question about saving elp
and EGI raw as a fif file.

I use raw = mne.io.egi.read_raw_egi() to read EGI raw data and elc =
mne.fiff.kit.read_elp() to read elp file.

How can I combine raw and elc and save them into one fif file?

Best

Xiaoxiao
