listbox, get items below selection

Hi. I have a listbox containing about 40 image filenames.

I want to select one (I do this using the mouse), and then take that one and the 5 filename below it and process them.

This is my code:

Selected = get(handles.listbox1, 'value')

for n = Selected:Selected+6
     tilect=1
     baseImageFileName = strcat(cell2mat(ListOfImageNames(n)))
     fullImageFileName = [folder '\' baseImageFileName];  % Prepend folder.         
     file=fullImageFileName    
     setappdata(0,'filename',file);   % Save for later
     IM = imread(file);       
     figure(findobj('Name','Tiles'))   %plot to figure already open
     subplot(1,6,tilect)
     tilect=tilect+1;

    end

But its giving me an error

Undefined function or variable "ListOfImageNames".

You need to load the image names into the cell array before you go into the loop:

ListOfImageNames = get(handles.listbox1, 'String');

Then in the loop I think you can just extract the string:

baseImageFileName = ListOfImageNames{n};
fullImageFileName = fullfile(folder, baseImageFileName);  % Prepend folder.

and don't use tilect at all. Just use

subplot(1,6, n);

thanks. I have to use tilect as sometimes the image I select is say 5th in the list, so my index n is from 5 to 11.

Oh, okay, right. Just don't set tilect = 1 at the top inside of the loop or it will never change.
