% POP_SELECTEVENT - Find events in an EEG dataset. If the dataset | |
% is the only input, a window pops up to | |
% ask for the relevant parameter values. | |
% | |
% Usage: >> [EEGOUT,event_indices] = pop_selectevent( EEG, 'key1', value1, ... | |
% 'key2', value2, ... ); | |
% Input: | |
% EEG - EEG dataset | |
% | |
% Optional inputs: | |
% 'latency' - [latency_range] latency range of events to include | |
% Ex: 'latency','400 <= 700' Include all events with | |
% latnecy in the range [400,700] | |
% 'omitlatency' - [latency_range] latency range of events to exclude | |
% 'type' - [type_range] event type(s) to include | |
% Ex: 'type',3 or [2 3 5] or 1:10 | |
% 'omittype' - [type_range], type(s) of events to exclude | |
% 'event' - [event_range], indices of events to include | |
% 'omitevent' - [event_range], indices of events to exclude | |
% 'USER_VAR' - [VAR_range], 'USER_VAR' is any user-defined field in | |
% the event structure. Includes events with values of | |
% field 'USER_VAR' in the specified range. Use [vector] | |
% format for integers, 'min<max' format for real numbers. | |
% 'omitUSER_VAR' - [VAR_range], 'USER_VAR' range of events to exclude | |
% 'select' - ['normal'|'inverse'] invert the selection of events. | |
% {Default is 'normal'} | |
% 'deleteepochs' - ['on'|'off'] 'on' = Delete ALL epochs that do not include | |
% any of the specified events {Default = 'on'}. | |
% This option is relevant only for epoched datasets derived | |
% from continuous datasets. | |
% 'invertepochs' - ['on'|'off'] 'on' = Invert epoch selection. {Default = 'off'}. | |
% 'deleteevents' - ['on'|'off'] 'on' = Delete ALL events except | |
% the selected events. {Default = 'off'}. | |
% 'renametype' - [string] rename the type of selected events with the | |
% string given as parameter. {Default is [], do not rename | |
% field}. | |
% 'oldtypefield' - [string] in conjunction with the previous parameter, | |
% create a new field (whose 'name' is provided as parameter) | |
% to store the (old) type of the event whose type has been | |
% renamed. {Default is [], do not create field}. | |
% | |
% Outputs: | |
% EEGOUT - EEG dataset with the selected events only | |
% event_indices - indexes of the selected events | |
% | |
% Ex: [EEGTARGETS,target_indices] = pop_selectevent(EEG,'type',[1 6 11 16 21]); | |
% | |
% % Returns ONLY THOSE epochs containing any of the 5 specified | |
% types of target events. | |
% | |
% Note: By default, if several optional inputs are given, the function | |
% performs their conjunction (&). | |
% Boundary events are keeped by default??. (6/12/2014 Ramon) | |
