[FieldTrip] questions about separating one dataset into two

[Tzvetan Popov]

Dear WanYu Hsu,

probably what you need is:
cfg =[];
cfg.trials = [1:50];
data1=ft_redefienetrial(cfg, data_Theta);
cfg.trials = [51:100];
data2=ft_redefinetrial(cfg,data_Theta);

alternatively have a look at the help of ft_selectdata.

Good luck,
Tzvetan
