% eegplot2trial() - convert EEGPLOT rejections into trial and electrode
% rejections compatible with EEGLAB format.
%
% Usage:
% >> [trialrej elecrej] = eegplot2trial( eegplotrej, frames, ...
% sweeps, colorin, colorout );
%
% Inputs:
% eegplotrej - EEGPLOT output (TMPREJ; see eegplot for more details)
% frames - number of points per epoch
% sweeps - number of trials
% 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:
% trialrej - array of 0 and 1 depicting rejected trials (size sweeps)
% elecrej - array of 0 and 1 depicting rejected electrodes in
% all trials (size nbelectrodes x sweeps )
%
% Note: if colorin is used, colorout is ignored
