Hi Nenad,

If I understand correctly what you want, ft_selectdata is what you are
looking for. You can use it to select specific trials or channels (or
time windows) from a data set. In the 'old' syntax, if you want trials
1, 3, and 5:

data = ft_selectdata(data, 'rpt', [1 3 5]);

Of course, the trial indices you will have to provide yourself, for
instance by looking at which trials originally came from which dataset
(i.e., prior to calling ft_appenddata).
