[FieldTrip] 'ft_redefinetrial' returning only one trial

[Rui Li]

hi,

cfg.begsample = [time(1); bad_times(:,2) + 1];
cfg.endsample = [bad_times(:,1) - 1; time(end)];

How about the rest three time samples: bad_times(:,2)+1, bad_times(:,1)-1
and time(end)?

Are they samples or the time?

Regards,
Rui.
