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)".

Here are a few steps you can take to troubleshoot:

• Ensure pushbutton1_Callback is correctly named and has the signature:

codefunction pushbutton1_Callback(hObject, eventdata, handles)

• Make sure the button's tag is pushbutton1 in the GUI editor.
• Update GUI Data: Use guidata(hObject, handles); after modifying handles.
• Check for errors in the callback, such as undefined variables or incorrect function calls.
• Ensure all required files (like images) are accessible and in the correct path.
• Version Compatibility: Check for any deprecated functions if using a newer MATLAB version.
