% 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
