this is the part of my code. i am trying to use matlab to train data. there is a folder named (label) and there are 400 pictures in this folder. and errors happen...

my english isnt that well. sorry..

hope someone can help me. thx a lot

------------------------------------------------------------------

%% generate data
filepaths = dir(fullfile(folder,'*.bmp'));
labelpaths  = dir(fullfile(folder,'*.bmp'));
for i = 1 : 380 %length(filepaths) 
    im_input = im2double(imread(fullfile(folder,filepaths(i).name)));  
    im_label =  im2double(imread(fullfile(labelfold,labelpaths(i).name)));   
    
    [hei,wid] = size(im_label);     
 
    for x = 1 : stride : hei-size_input+1
        for y = 1 :stride : wid-size_input+1
            
            subim_input = im_input(x : x+size_input-1, y : y+size_input-1);
            subim_label = im_label(x+padding : x+padding+size_label-1, y+padding : y+padding+size_label-1);
            count=count+1;
            data(:, :, 1, count) = subim_input;
            label(:, :, 1, count) = subim_label;
        end
    end
end
order = randperm(count);
data = data(:, :, 1, order);
label = label(:, :, 1, order); 

my version is R2018b

You did not have at least 380 different .bmp files in the folder.

Note: you use the same folder for filepaths and labelpaths when doing the dir(), but you use different folder names when duing the fullfile for imread purposes.
