How can I collect 3d-data while a Matlab-GUI is in process?

Hello,

I have manage to connect a 3d-data-collector device with Matlab. Actually I get the 3-d data that device collects through Matlab. When I run my code a Matlab GUI appears on the screen and on the first touch of the user on the screen I enable the 3d-data recording procedure on the device. I want GUI and data collection to run in parallel, but they don't. When data collection starts Gui does not work properly. I use matlabpool but still it does not work as I want. Here is my code:

 matlabpool open 4;    % Use default parallel configuration

    spmd          % By default uses all labs in the pool
        strct.socket = libclient('0.0.0.0', 7234, 2);
    end

matlabpool close;

 set( a.uipanel1 ,'Visible', 'off')
 set( a.uipanel2 ,'Visible', 'on')

This is the code that there is in uipanel1_ButtonDownFcn. After that function I want to collect data continually until I will stop the application and I also want uipanels of my intreface to alternate there visibility non-stop until I will stop the application.

Do you think I should use a different method instead of matlabpool or it is correct but there is something wrong with my code?

Thank you....
