Error reading mutiple files with 'importdata'-Loop

Hi, I'm trying to develop a GUI for some image processing. I'm already stuck at reading in the 'raw' .csv files. My code for importing the data so far:

[flnm,flpth,cCheck] = uigetfile('*.csv',...
                                'Select the Data File',...
                                'Multiselect','on');

if (cCheck ~= 0)
    set(handles.List,'Value',1);

      set(handles.List,'String',flnm);
  end

z = size(flnm);
z = z(1,2);

Store = rand (511,640,z);

delimiterIn = ',';
headersIn = 530;
Raw = cell(530,z);

for s =1:z

Raw(:,s) = importdata(flnm{s,1},delimiterIn,headersIn);

Raw(:,s) = strrep(Raw(:,s), ',','.');
Raw(:,s) = strrep(Raw(:,s), ';',' ');

end

In this case the result of the import data function is a 530 by 1 column-vector. I want to store mutiple of these in the cell-array 'Raw'. Unfortunately the 'importdata-Loop' just works in its first iteration -> just the first column of the 'Raw' got filled.

The following Error appears:

Index exceeds matrix dimensions.

Error in SlideGui>pushbutton1_Callback (line 126)
Raw(:,s) = importdata(flnm{s,1},delimiterIn,headersIn);

Error in gui_mainfcn (line 96)
        feval(varargin{:});

Error in SlideGui (line 42)
    gui_mainfcn(gui_State, varargin{:});

Error in @(hObject,eventdata)SlideGui('pushbutton1_Callback',hObject,eventdata,guidata(hObject))

Error while evaluating uicontrol Callback

Has anybody an idea why the Loop index exceeds the dimension of any matrix?

Thanks a lot, Mark

I think it's the size of flnm.

z = size(flnm);
z = z(1,2);

This indicates that flnm is a row of filenames. But

importdata(flnm{s,1},delimiterIn,headersIn);

indicates that it is a column. Try

importdata(flnm{1,s},delimiterIn,headersIn);

Thank you so much!
