Dear dcp users

I've installed the dcp2 pipeline yesterday and the GUI starts without any problems. However, when I put in a directory with T1 and DTI data it says:

Index exceeds the number of array elements (0).

Error in DCP_checkOpt>DCP_checkInput (line 11)
if strcmp(sub(3).name, '.DS_Store')
Error in DCP_checkOpt (line 2)
[flag,sub]=DCP_checkInput(opt.inputFile,opt.sub);
Error in DCP>pushbutton17_Callback (line 421)
[flag, errorMsg]=DCP_checkOpt(opt);
Error in gui_mainfcn (line 95)
feval(varargin{:});
Error in DCP (line 42)
gui_mainfcn(gui_State, varargin{:});
Error in
matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)DCP('pushbutton17_Callback',hObject,eventdata,guidata(hObject))
Error using matlab.ui.internal.dialog.FolderChooser/doShowDialog (line 70)
Error while evaluating UIControl Callback.

What am I doing wrong?

Best wishes & thanks for the help
