[FieldTrip] Reading events from a trigger channel

[Harsimrat Singh]

Hi Fieldtrippers

My data is in edf format but has a event marker channel in the form of
pulse on channel 1.

I have tried to use
event =
ft_read_event(cfg.datafile,'trigindx',1,'threshold',5e2,'detectflank','up');

But 'detectflank' doesn't seem to work.
Is it particular for MEG data format (yokogawa).

Can some one give me an idea how to define pulses on channel trials in
define trial. The channel has same Fs as data channels.

Thanks for your help in advance.

Best regards
Harsimrat
