I have a function which works with a file selected from the user using a an edit callback. The function does not work inside the funtion callback, how can I put my function out side the function callback?

I have a function that works with an image the user selects (measure11). The user pastes the path of that image in a UI edit (uicontrol('style','edit',...)). The problem is that for some reason, the function that works with the image does not work when it is inside the function callback of the edit. I need to do a "trick" to make the function work with the image right when the user selects an image but so it is not inside de function callback

This is what I have so far

function temmporal
filename=0;
f = figure('Visible','on','Position',[360,500,450,185],'NumberTitle','off','ToolBar','none','MenuBar','none','Color',[0.95 0.95 0.95]);
hEdit = uicontrol('Style','edit','Position',[25 50 400 20], 'Callback',@edit_Callback);

       while exist('filename','var')==1
           edit_Callback
           x=measure11(filename);
            break
       end    
       function edit_Callback(source,eventdata)
             a = get(hEdit,'string');
             [filename, pathname] = uigetfile({'*.jpg';'*.bmp';'*.tiff';'*.png'} ,...
             'Select file to be analyzed',a); close all
       end
  end

But clearly using a "while" loop did not work. The function that works with the image is the one called "measure11" and the image itself is called "filename".

This makes the function (measure11) not work properly:

function edit_Callback(source,eventdata)
           a = get(hEdit,'string');
           [filename, pathname] = uigetfile({'*.jpg';'*.bmp';'*.tiff';'*.png'} ,...
           'Select file to be analyzed',a); close all;  x=measure11(filename); 
     end

In this case the function (measure11) works alright but will run when the user hasn't selected an image yet:

   x=measure11(filename);
  function edit_Callback(source,eventdata)
             a = get(hEdit,'string');
             [filename, pathname] = uigetfile({'*.jpg';'*.bmp';'*.tiff';'*.png'} ,...
             'Select file to be analyzed',a); close all
       end

You are not saving the filename or pathname after you obtain them from the user. See http://matlab.wikia.com/wiki/FAQ#How_can_I_share_data_between_callback_functions_in_my_GUI.3F

I'm sorry, I do not understand
