function varargout = profiles(varargin) 
% GUI for plotting profiles for image arrays 
%   Plots Z-profile (through stack of images for a chosen pixel) 
%   Plots line profile for line drawn in an image, and plots 
%   profiles for the same coordinates for different images in array 
%    
% INPUT: 
%   images - array to threshold images (can be a single image as well) 
%   'N' - image to display  
% 
% to run: 
% 
%   profile(images,'1')
