[Eeglablist] Reject random epoch

[Stephen Politzer-Ahles]

Hi Carlos,

The MATLAB function randsample() can get random numbers. So you could use
that, in combination with the pop_rejepoch() function, to randomly remove
some epochs. If you want to do this many times, just use a 'for' loop to
repeat it over and over again.

num_epochs = size(EEG.data, 3); % Find the number of epochs
num_toreject = 5; % Some number of epochs to reject per file; you can set
this to any integer you want
epochs_to_reject = randsample( 1:num_epochs, num_to_reject ) % Get some
random epoch indices (without replacement)
EEG = pop_rejepoch( EEG, epochs_to_reject, 0 ); % remove those epochs

Best,
Steve
