[Mne_analysis] Question about digital trigger channel for Neuromag-122 data

[Yang Zhang]

I am looking for help on how to set up the digital trigger channel 
correctly for analyzing Neuromag-122 raw data using MNE.
I did trial-and-error in changing STI 001 ... 006, 015, 016,  to STI 014 
one at a time,  but each time, the event numbers were incorrect (over 
20,000 events were found) in doing mne_process_raw. mne_fix_stim14 did 
not help remove the problem.
I tried to senenv for trigger channel to be one of the STI channels in 
the raw data, but the events were not detected at all.

Your advice is greatly appreciated.
