[FieldTrip] Trigger channel for edf

[David Iglesias López]

Hi Robert,

And the end I got it before like this:

cfg                 = [];  
cfg.dataset      = filename;
cfg.continuous = 'yes';
cfg.trialfun       = 'trialfun_david';
cfg                 = ft_definetrial(cfg);
dataout          = ft_preprocessing(cfg);

And it worked nicely.

Thank you,

David
