When typing the following code:
[w,~] = listdlg('PromptString',{strcat(['Select a wing for ' ,...
'individual number ',num2str(indx)])},...
'SelectionMode','single','ListString',fn);
It doesn't show the words after 'individual'
I wonder why...
Thanks,
Ziv

It wouldn't be a bug since this behavior is documented in the doc.
"If you specify the prompt as a character vector that is longer than the width of the dialog box, the prompt clips. To create a multiline list box prompt, specify the prompt as a cell array or string array. Line breaks occur between each array element. Long elements wrap to fit the dialog box."
Your prompt string is longer than the width of the box. You could try the following.
[w,~] = listdlg('PromptString',["Select a wing for ",...
"individual number " + num2str(indx)],...
'SelectionMode','single','ListString',"Happy");
