parallel pool error

Hi, Dr. Yan, When I regressed covariates of 200 subjects using latest DPARSF,  an error was shown as below. However, it was fine when I computed just two subjects.

error in distcomp.remoteparfor/getCompleteIntervals (line 133)
The parallel pool that parfor was using has shut down. To start a new parallel pool, run your parfor code again or use parpool.

error in DPARSFA_run (line 3388)
        parfor i=1:AutoDataProcessParameter.SubjectNum


error in DPARSFA>pushbuttonRun_Callback (line 1786)
    [Error]=DPARSFA_run(handles.Cfg);


error in gui_mainfcn (line 95)
        feval(varargin{:});

error in  DPARSFA (line 30)
    gui_mainfcn(gui_State, varargin{:});

 
计算 UIControl Callback 时出错
