[Eeglablist] remove entire rows from EEG.event

[Andreas Widmann]

[ EEG.event( strcmp( 'boundary', { EEG.event.type } ) | strcmp( 'R  1', { EEG.event.type } ) ) ] = [];

EEG.event (length) must not change during the loop execution. Besides exceeding EEG.event length you will also miss successive to be removed events. For loop works if you first collect events and remove afterwards, e.g.

removeIdxArray = [];
for b = 1:length(EEG.event)  
    
         if strcmp(EEG.event(b).type, 'boundary')
            removeIdxArray = [ removeIdxArray b ];
         elseif strcmp(EEG.event(b).type, 'R  1')
            removeIdxArray = [ removeIdxArray b ];
         end
         
end
EEG.event( removeIdxArray ) = [];

Hope this helps! Best,
Andreas
