[Eeglablist] Save epoch subsets

[Andreas Widmann]

You overwrite your "mother" dataset:
> EEG = pop_select( EEG,'trial',[1:30] );

Try:
EEG = pop_loadbva(filliste(n).name);
TMP = pop_select( EEG,'trial',[1:30] );
pop_saveset( TMP, 'filename',new_filename,'filepath',savedir);
TMP = pop_select( EEG,'trial',[31:60] );
...


Hope this helps! Best,
Andreas
