function [x y width height] = art_slice2pos(slice,locate)
% this function accepts the 'locate' variable from art_movie.
%
% INPUT:
% slice - the slice number  to find position of,
% locate - values of the displayed layout
%               locate(1) = plane (axial, saggital, coronal)
%               locate(2) = number of rows
%               locate(3) = number of columns
%               locate(4) = slice resolution in X direction
%               locate(5) = slice resolution in Y direction
%
% OUTPUT
% [x y width height] - ready to use variables for positioning the red
% rectangle for a bad slice
