[Eeglablist] pop_eegplot v12 0 2 4b

[Mikołaj Magnuski]

I thought I'd add an example and
correct my previous explanation:

I should have written:
for each row (that is segment marked for rejec-
tion) first column defines its start sample and se-
cond _column_ the end sample). This information, if sa-
ved, should be enough to recover rejections at so-
me later time.

example of removing continous signal with TMPREJ:
Having the matrix TMPREJ in workspace
you can remove the all segments marked for
rejection:
EEG = eeg_eegrej(EEG, round (TMPREJ (:, 1:2) ) );
% and overwrite the dataset (assuming the current one is the one TMPREJ
refers to):
[ALEEG, EEG, CURRENTSET] = pop_newset (ALLEEG, EEG, CURRENTSET, 'gui',
'off', 'overwrite', 'on');
