I am developing a code to show a gif image during matlab processing. When the process is finished, the gif image is closed and the result would be plotted. However, the gif image is stopped when the matlab processing is being processed.

gif_image='C:\Users\Amir\Desktop\spinner.gif';
[handles.im,handles.map] = imread(gif_image,'frames','all');
 handles.len = size(handles.im,4); % number of frames in the gif image
 delay_length = 0.2;
axes(handles.axes1)
hold(handles.axes1,'on');
imshow(handles.im(:,:,:,1),handles.map);
handles.count = 1;% intialise counter to update the next frame
handles.guifig = hObject;
handles.tmr = timer('TimerFcn', {@TmrFcn,handles.guifig},'BusyMode','Queue',...
'ExecutionMode','FixedRate','Period',delay_length); %form a Timer Object
guidata(handles.guifig, handles);
start(handles.tmr); %starts Timer
% Update handles structure
guidata(hObject, handles);

when this part is going to begin, showing the gif image is stoped. :(

try
[matlabImage mask1 col col1 x y boundaries]=read_img();

What is the contents of TmrFcn()? Is this still executed during the computations? If not, this would be a better description: "The timer callback is not executed during processing".

Does it work in the Java level: http://undocumentedmatlab.com/blog/displaying-animated-gifs ?

Thanks for your respond. As I already wrote, I want to show wait gif when the processing is running. Do you mean, my code is wrong or the matlab has bug?
