Dear Dr. Deshan Yang

I am writing this to seek assistance in loading the images in to DIRART suite through cerr plans. The following error occurs while loading,


Error using cd
Cannot CD to  (Name is nonexistent or not a directory).
Error in ART_Load_Structure_CERR (line 63)
cd(meshDir);
Error in Load_2_Images (line 48)
            [structs,assocScanIDs,scanInfos] = ART_Load_Structure_CERR(planC);
Error in reg3dgui>Load_Images_From_CERR_Plans_Menu_Item_Callback (line 340)
Load_2_Images(handles,2);
Error in gui_mainfcn (line 96)
        feval(varargin{:});

Error in

I would appreciate if you could assist me in this regard.

Thanks in advance
