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:

Concatenating strings to create the filename is the problem.
Use fullfile instead, your code will work fine.

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.
