I want the .txt message ([Nodelocation]) read by pushbutton2 to be used on pushbutton1, but pushbutton1 can't read the data of pushbutton2. How do I write it?
function pushbutton2_Callback(hObject, eventdata, handles)
[file,filepath] = uigetfile('*.txt');
if isempty(file); return; end %user cancel
fullname = fullfile(filepath, file);
[Nodelocation] = textread(fullname);
% --- Executes on button press in Topology.
function pushbutton1_Callback(hObject, eventdata, handles)
[UElocation] = textread('observe/mdUELocationforGUI2.txt');
[AssignCell] = textread('observe/AssignCell.txt');
cla(handles.axes1,'reset');
axes(handles.axes1);
for ii=1:length(Nodelocation(:,1))
for jj=1:length(UElocation(:,1))
if AssignCell(jj,2) == Nodelocation(ii,1)
if Nodelocation(ii,1) == 0
scatter(Nodelocation(ii,2),Nodelocation(ii,3),150,[1 0 0],'^','filled');
hold on;
scatter(UElocation(jj,2),UElocation(jj,3),50,[1 0 0],'x');
hold on;
end
end
end
end

Store the result back to your guidata struct in your first callback.
You do need to make sure that clicking on the second button first does not cause any errors.
