You got a solution in your other thread already: https://www.mathworks.com/matlabcentral/answers/809300-dot-indexing-is-not-supported-for-variables-of-this-type
A 3rd thread with the same question is closed. Please stay at one question per problem. Thanks.

Obviously you're either not getting into the 'if' or you're not getting into the 'for', and so the Group_Test1 never gets assigned. Here is how to solve it:

Why are you starting the loop at 3 when you've already removed the . and .. from cell_array_of_folder_names? It should start at 1. And there is no name field of the string in the cell. It's just a regular character array, not a structure.
sad = dir('D:\Project\DB1\test\'); % Returns both folders and files
% sad = dir(pwd); % Returns both folders and files
cell_array_of_folder_names = {sad([sad.isdir]).name}; % Select folder names
% cell_array_of_folder_names( strncmp( cell_array_of_folder_names, ".", 1 ) ) = []; % Remove '.' and '..'
sorted_cell_array_of_folder_names = sort_nat( cell_array_of_folder_names );
% sorted_cell_array_of_folder_names = cell_array_of_folder_names; % if you don't have sort_nat
whos sorted_cell_array_of_folder_names
%----------------
[mp1, np] = size(sorted_cell_array_of_folder_names); % compute size = number of subfolders & files & . & ..
csf1=0; % counter of JUST subfolders found in PF
t=1;
for i=1:mp1
% Skip . and ..
if endsWith(sorted_cell_array_of_folder_names{i}, '.') || endsWith(sorted_cell_array_of_folder_names{i}, '..')
% Skip . and ..
continue; % Skip to bottom of loop.
end
% Keep only folders:
csf1 = csf1 +1; % one sub folder found
SFN = sorted_cell_array_of_folder_names(i).name ;% extract his name
tifList = ls(sprintf('%s%s%s%s',PF,SFN,'\','*.tif')); % list all jpg files
[ms1, ns] = size(tifList); % ms = number of image files found
% Processing for each tif file:
for j=1:ms1
tifFileName = tifList(j,:); % extract name of tif file
% IM=imread([PF SFN '\' tifFileName]);
%t=1;
%for i=1:csf1
% for j=1:ms1
Group_Test1(t)={i-2};
t=t+1;
end
PF_SFN_imgName = sprintf('%s%s%s',PF,SFN,'\',tifFileName);
end
% save('Group_Test','Group_Test1');

Before the loop
Group_Test1 = zeros(1, mp1);
In the loop:
Group_Test1(t) = i - 2;
After the loop
Group_Test1 = Group_Test1(1:t-1); % Crop off any unused elements
