% eegplot2event() - convert EEGPLOT rejections into events
% compatible with the eeg_eegrej function for rejecting
% continuous portions of datasets.
%
% Usage:
% >> [events] = eegplot2event( eegplotrej, type, colorin, colorout );
%
% Inputs:
% eegplotrej - EEGPLOT output (TMPREJ; see eegplot for more details)
% type - type of the event. Default -1.
% colorin - only extract rejection of specific colors (here a n x 3
% array must be given). Default: extract all rejections.
% colorout - do not extract rejection of specified colors.
%
% Outputs:
% events - array of events compatible with the eeg_eegrej function
% for rejecting continuous portions of datasets.
%
% Example:
% NEWEEG = eeg_eegrej(EEG,eegplot2event(TMPREJ, -1));
