dear chaogan，
我在matlab2010b里装载了dparsf2.0，但是打开以后点选工作路径的时候弹出提示框按ok之后没有反应，命令行出现如下字段：
??? Attempt to reference field of non-structure array.

Error in ==> DPARSF>btnSelectWorkingDir_Callback at 247
theDir =handles.Cfg.WorkingDir;

Error in ==> gui_mainfcn at 96
feval(varargin{:});

Error in ==> DPARSF at 41
gui_mainfcn(gui_State, varargin{:});
