Hello.
I am trying to make GUI that processes an images in slides.
But I am having trouble with the radio buttons. You're supposed to be able to choose one when the GUI is first initiallized and then depending on which radio button is chosen the image will show in rgb or grayscale. The trouble happens when I run the GUI and try to choose gray scale it immidiatle deactavates the buttons so that I can't choose either. When RGB is selected the program runs fine and then it won't let me re run it to select another radio button. Any help with this would be greatly appreciated.
function varargout = gui_flybrain(varargin)
% GUI_FLYBRAIN MATLAB code for gui_flybrain.fig
% GUI_FLYBRAIN, by itself, creates a new GUI_FLYBRAIN or raises the existing
% singleton*.
%
% H = GUI_FLYBRAIN returns the handle to a new GUI_FLYBRAIN or the handle to
% the existing singleton*.
%
% GUI_FLYBRAIN('CALLBACK',hObject,eventData,handles,…) calls the local
% function named CALLBACK in GUI_FLYBRAIN.M with the given input arguments.
%
% GUI_FLYBRAIN('Property','Value',…) creates a new GUI_FLYBRAIN or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before gui_flybrain_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to gui_flybrain_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
