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

If you're not going to bother describing where the actual problem occurs and what the error is, I'm not going to bother reading 3 pages of mostly irrelevant GUIDE-generate spam.

Have a read here and here. It will greatly improve your chances of getting an answer.
