[Eeglablist] Using variables in pop_selectevent

[Cedric Cannard]

Dear Arkadiy,

Here is the code to do what you need for events with a latency below 10000 samples (to edit with your fastval value). Note: this will convert all your events to character strings (which should not pose a problem later for STUDY). 

% index of events with latency below your threshold
evToRename = [EEG.event.latency] <= 10000; 

% Loop through events and rename events of interest using that index 
for iEv = 1:length(EEG.event)
    if evToRename(iEv)
        EEG.event(iEv).type = 'fastRTs';
    end
end
EEG = eeg_checkset(EEG);
