MATLAB: How to call old GUI in the current working GUI

Question

I have a current running GUI in which I need to pick an image.

Later, I want the same Image that I picked now to be present in the old GUI that I gonna call.

HERE IS THE CODE OF THE CURRENT RUNNING GUI:

%In the current running GUI I'll pick an image

 axes(handles.axes1);
 global ImageOriginal
 [baseFileName,folder]=uigetfile('*'); % read the input image

 ImageOriginal=imread([folder,baseFileName]);
 imshow(ImageOriginal);

HERE IS THE PLACE I CALL THE OLD GUI BY THE HELP OF A PUSH BUTTON:

 manual_ImageGUI %this is the .m file of my old GUI. I call it in the Current GUI

%But the problem is, when I call this "manual_ImageGUI", again i need to pick an image in it. What i need is, as i already chose the image in the current GUI it should be used in the old GUI too when i call it.

The code in Manual_ImageGUI is :

 axes(handles.axes1);
 global ImageOriginal
 [baseFileName,folder]=uigetfile('*'); % read the input image
 im=imread([folder,baseFileName]);
 [~,~ , numberOfColorChannels]=size(im);
if numberOfColorChannels > 1
 %  im = rgb2gray(Iinitial);  % converts to gray scale
 else
  im = Iinitial; % It's already gray.
 end
 im1=imadjust(im);
 imshow(im1);

any help is appreciated… thanks

I'd just create the full filename with fullfile() and then write that out to a mat file that your second GUI can read in.

fullFileName = fullfile(folder, baseFileName);
save('myApp.mat', 'fullFileName');

To recall

storedStructure = load('myApp.mat');
fullFileName = storedStructure.fullFileName;
