Dear SPM experts, 

I'm using spm_eeg_fuse to fuse EEG data (62 channels) with MEG data (248 channels). 

After fusion, for D.sensors('MEG') I get the 248 MEG channels. However, for D.sensors('EEG') I get 348 channels!

D.modality returns 'Multimodal'. D.sensors('EEG').label returns strange looking labels such as: 

'FFT9h'

'FFT7h'

'FFC5h'

'FFC3h'

'POO2h'

'POO4h'

'POO6h'

'POO8h'    

'AF7h'

'AF5h'

'AF3h'

'AF1h'

This is on top of the actual 62 EEG channels. 

I see these additional channels when I display the EEG channels after 3-D source reconstruction, but not when I display them using display > M/EEG > EEG scalp (see figures). 

Same results with SPM8 and SPM12b. 

What's going on here? 

Thanks for your help, 

Roni Tibon
