Trouble importing events in yokogawa data

Hi,
I am having a trouble in importing raw MEG data (in yokogawa .con file).

Our MEG system has 128 channels (64 MEG channels and 64 additional analogue channels). Some analogue channels were used as trigger channels (e.g. No.65, 66, 67 ...), and the remainings were empty. When reviewing raw data using Brainstorm, there's no error message, and no triggers or events were recognized. The 64 MEG channels were well recognized, and their labels were "AG000, AG001,....AG063" in the channel file. The additional 64 analogue channels were named "Null001, Null002..." and nothing were imported. If I use other toolbox, like Fieldtrip, I can read the events with MEG data. It seems that events were stored in the raw data, but Brainstorm ignored them when reviewing the data? Do you have any idea to fix this problem?
I have uploaded a sample data with triggers at No.65 channel in cloud (a bigger one: http://u.163.com/nnnnnn8zP retrieving code: 1l3BZXlL, and a small one: http://u.163.com/nnnnnU7R retrieving code: QN4aeu9I).

Thank you very much!

Best,

Select the "Link to raw file" in the Process1 list, and run the process "Events > Read from channel".

Thank you for your reply! It helps a lot!
