I toke my datas with an MEG from 'Neuromag' with 122 Channels. When I load the raw.fif-File with mne_browse_row I have to select the chanels and the event-Triggers separately under the menu-point 'Adjust---Selection...' this far no problem. Now I want save the event-file under the menu-point 'File--save events', but the message is "no events to save". In the Manual is a discription-point under chapter 4.4.1.1. that: trigger channel STI 014 is scanned for events. In my raw-datas is no STI 014, but STI 016. Is this the problem? And when yes, how can I get my event-file?
Thanks for your ideas!

I must admit that I had forgotten that there is no composite trigger
channel in Neuromag 122. Instead, there are six trigger channels:
'STI 001' ... 'STI 006' which together constitute the trigger input.
If you have only one trigger on one of those channels in your data,
the solution is simple: use the --digtrig option, e.g., --digtrig
STI_001 and you will be able to create the event file.
For the case of multiple triggers, the solution is a little bit more
complex, let me look into that.
