Opening other GUI with radio button

I have a Button Group and I want to show another GUI when I clicked on one of the radio buttons but I don't know how to call the file. What command or syntax do I need to use? Can anybody help me, Thanks.

RadioButtons are designed to select mutual exclusive conditions. Opening another GUI by a RadioButton might be unintuitive. I'd suggest a PushButton.

In you radio callback function you can directly call other GUI. For example

function radiobutton1_Callback(hObject, eventdata, handles)
if get(hObject,'Value')==1
    gui1;
else
    close gui1;
end

This code will open gui1 when radiobutton1 is selected and closes gui1 when same is deselected.
