Below is my GUI code;

function varargout = GUI(varargin) % GUI MATLAB code for GUI.fig % GUI, by itself, creates a new GUI or raises the existing % singleton*. % % H = GUI returns the handle to a new GUI or the handle to % the existing singleton*. % % GUI('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in GUI.M with the given input arguments. % % GUI('Property','Value',...) creates a new GUI or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before GUI_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to GUI_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one % instance to run (singleton)". % % See also: GUIDE, GUIDATA, GUIHANDLES

I am having trouble as i need to refer to the avi file which is loaded into the GUI to play it and produce a still image from it however no variables are created for it in the workspace so how do I refer to it or import the avi file back to the workspace so i can refer to it?

Also i need to refer to the points chose when digitised however the points only appear in the command window and do not show in the workspace, what code would I need to write to save the x,y coordinates as a variable which I can use for my calculation to produce the still image.

Thanks
