 The configuration structure will contain the fields cfg.dataset, cfg.headerfile and cfg.datafile. If you want to pass additional information (e.g., trigger value), then you should do that in the sub-structure cfg.trialdef.xxx. The second output argument of the trialfun is optional, it will be added to the configuration if present (i.e. for later reference).

 ### Rising flank of a TTL trigger
 
-The example scripts assume that the event is marked by an 'up' flank in the recorded signal (e.g., by virtue of an increase in light on the photodiode transducer). Downward going flanks can also be detected by specifying cfg.detectflank = 'down'. The trigger threshold can be a hard threshold, i.e., numeric, or flexibly defined by an executable string, for example to calculate the 'median' of the analog signal.

 In this example, we define a 'segment' or 'trial' as one second preceding this trigger until 2 seconds thereafter:
