MATLAB: Dir function gives nothing

Question

I am using Dir function to find the specific files that have cell in their names but it retunrs nothing although cell files are existing in that folder. Here is the code:

selpath = uigetdir;
struct = dir([selpath '*cell*.json']); 

and here is the sample image of the folder:

Answer 1

selpath = uigetdir;
if isempty(selpath); return; end  %user cancel
dinfo = dir(fullfile(selpath, '*cell*.json')); 

uigetdir() does not promise that what it returns will end with a directory separator, so use fullfile()

Using struct as a variable name would interfere with creating structures.
