The figure closed after pressing push button?

Guys, I am creating a figure and I have in that figure a push button for executing *.m file. after pressing in that push button the figure will be closed immediately. How to prevent the figure to be closed?

the code I am using is simple as follows:

% --- Executes on button press in btnProceesImage.
function btnProceesImage_Callback(hObject, eventdata, handles)
parasite1;
viewresults;

Maybe you have in one of the two functions the command "close" or "close all" ? This command closes all opened figures.
