How to store the result of areas on every images on loop in one folder to workspace?

i keep getting an error and it only loaded some of the image not all of them, i have like 600+ files but it only loaded for 19 images idk why

clc; clear; close all;

folder_nrml = ('/Users/*/Documents/MATLAB/regionbased_seg/cv/NORMAL');

file_nrml = dir(fullfile(folder_nrml, '*jpeg'));

jumlah_file_nrml = numel(file_nrml);

training_data_nrml = zeros(jumlah_file_nrml);

calc = [];

for l = 1:jumlah_file_nrml

I = imread(fullfile(folder_nrml, file_nrml(l).name));

figure, imshow(I)

bw1= im2bw(I);

bw2 = imfill(bw1,'holes');

s = regionprops(bw2, 'centroid', 'area');

centroids = cat(1, s.Centroid);

area = cat(1, s.Area);

sum_area = sum(area);

hold on

plot(centroids(:, 1), centroids(:,2), 'r*')

[B,L] = bwboundaries(bw2, 'noholes');

[~,l]= bwlabel(bw2,4);

for k = 1:l

boundary = B{k};

plot(boundary(:,2), boundary(:,1), 'y', 'LineWidth', 2)

text(boundary(1,2), boundary(1,1), strcat(['Area = ',num2str(area(k))]), 'Color', 'r', 'FontSize',15, 'FontWeight','bold');

end

calc = [calc;sum_area];

cell_areas(l,:) = {file_nrml(l).name, sum_area};

hold off

end

here are the result and error
