Hello, I'm new to MNE and having a problem importing data, I seem to lose  
my triggers. The original EEG data is in Biosemi's .bdf format and looks  
fine, and I've converted it to .fif using mne\_edf2fiff. When I open the  
file with mne\_browse\_raw using 'Status' as trigger channel, the program  
claims to find a reasonable amount of events. However, the 'Status'  
channel looks empty, as is the event list from 'Windows -\> Show event  
list'. From the print 'max\_event: 0' it sounds like the values are somehow  
missing?

mne\_browse\_raw --raw tmp.fif --digtrig Status  
...  
Scanning Status for triggers...[done]  
3229 events found in tmp.fif  
Trigger channel : Status max\_event : 0

Thanks for any ideas,  
Suvi
