[Mne_analysis] Writing EEG (.edf, .mat, or .txt) data to .fif with MEG data

[tapsya at nmr.mgh.harvard.edu]

Hi Brian,

Please ignore my previous message, it was incomplete and had no
attachment. [I hit 'send' by mistake. Apologies!!].

To convert .edf to .fif please use the command 'mne_edf2fiff'.

Usage:
mne_edf2fiff --edf your_edf_file_name.edf --fif
your_resultant_fif_file_name_raw.fif

In this email, you will find my code as an attachment which is a matlab
code 'Combine_fiff.m'. This code accepts two .fif files with different
sampling frequencies, matches it and then synchronizes the triggers.
Sounds like you do not need it and plus it will not work for you [since
you will need another .m file for it to work].

However, the code does contain mne matlab commands to combine two .fif
files into one and will help you also to handle the header information for
the new .fif file. I have commented sections in the code which I think may
be helpful to you.

Hope this helps. Let me know if you have further questions.


Thanks.

Wishes,
Tapsya Nayak

Convert the EEG to fif with mne_edf2fiff and then merge the 2 fif files
with matlab or python. Assuming the timings are good, it should consist in
concatenating the channels and the data. It's not
