Exporting epochs: "MEG sensors are currently not supported by this function."

Hello! I am currently trying to export the epochs into .mat SPM files. While trying to export the epoch pack, I got the following error message:

Error using export_data (line 252)
Error using out_fopen_spm (line 84)

Thank you very much

Since the SPM analysis requires data in SPM format including both the time series and sensor information (it doesn’t seem to support the source file), I tried to apply “export to file” and selected the SPM format to the epoched data. However, I was not able to finish the export because of …
