[Eeglablist] Removing event manually

[Isil Bilgin]

Dear Martin,

Just addition to Dan's suggestion, if you know the index of the epochs you
want to remove from you can also create an array of those event indices
(e.g. events2remove) and feed it to the below EEGLAB function which should
remove the unwanted events without harming the EEGLAB data structure.

EEG = pop_select( EEG,'notrial',events2remove);

Hope it helps,

Kind regards,
