Hi guys,

After i use the following code to find files i want, how to put those files into the new folder? Thank you.

This code will give me the info of files in a struct such as name, path, size etc.

files = dir('D:\Data\**\*.mat')

To confirm: even though each of the level 3 folders has 100+ files, you want to extract only the one where the "cell" number prefix matches the folder name? Does it happen to be the case that those are the only cell*_Area.csv files in those folders? For example, there is no cell1_Area.csv inside MDA cell2 that needs to be ignored because the cell# prefix does not match the folder name ?

Hi Walter

Sorry for the late reply.

Each csv file's name is unique and the cell# prefix matches the folder name.

For example: in folder 'MDA cell1', all of csv file is 'cell1_Area','cell1_distance'.... There is no cell2_* in folder 'MDA cell1'.

Hi Walter

Thank you. i tried it and i got the folder 'Area', but its empty. At the same time, i got an error: 'Error using copyfile

Arguments must contain a character vector.'

When i check 'fullnames', its a cell array. I cant figure out which went wrong. I need your help. Thank you. :)

Here is my original full name of files in matlab. Everything looks fine, but i can not run 'copyfile' successfully.

The following is my original code:

destdir =  'D:\Data\MDA231 Matlab\Area';
files = dir('D:\Data\MDA231\MDA231 Mito cell*_Statistics\MDA231 Mito cell*_Area.csv')
fullnames = fullfile({files.folder}, {files.name});
if ~exist(destdir, 'dir')
    mkdir(destdir);
end
copyfile(fullnames, destdir); 
files = 
  10×1 struct array with fields:
    name
    folder
    date
    bytes
    isdir
    datenum
Error using copyfile
Arguments must contain a character vector.

Please check fullnames:

 filenames=char(fullnames)
filenames =
  10×72 char array
    'D:\Data\MDA231\MDA231 Mito cell10_Statistics\MDA231 Mito cell10_Area.csv'
    'D:\Data\MDA231\MDA231 Mito cell1_Statistics\MDA231 Mito cell1_Area.csv  '
    'D:\Data\MDA231\MDA231 Mito cell2_Statistics\MDA231 Mito cell2_Area.csv  '
    'D:\Data\MDA231\MDA231 Mito cell3_Statistics\MDA231 Mito cell3_Area.csv  '
    'D:\Data\MDA231\MDA231 Mito cell4_Statistics\MDA231 Mito cell4_Area.csv  '
    'D:\Data\MDA231\MDA231 Mito cell5_Statistics\MDA231 Mito cell5_Area.csv  '
    'D:\Data\MDA231\MDA231 Mito cell6_Statistics\MDA231 Mito cell6_Area.csv  '
    'D:\Data\MDA231\MDA231 Mito cell7_Statistics\MDA231 Mito cell7_Area.csv  '
    'D:\Data\MDA231\MDA231 Mito cell8_Statistics\MDA231 Mito cell8_Area.csv  '
    'D:\Data\MDA231\MDA231 Mito cell9_Statistics\MDA231 Mito cell9_Area.csv  '

Hi Walter

Thank you so much. It works very well. it saved me tons of time. I have 2000 csv files need to be sorted like this.

What if the output data has to save in an excel/csv format in a different folder. Here the the output of Analysis1 wants to save in a new excel/csv file in different folder or soeother directory. Please help me with this code.

% getting the folder directory of files you want to work
myFolder = '/Users/xxxxx/Desktop/xxxxx/Tests/27.11.2020 csv/Total';
% code for determining the file pattern that you have, * represents all the
% files
filePattern = fullfile(myFolder, '*.csv');
% code for addressing all the files
theFiles = dir(filePattern)
for k = 1: length(theFiles)
    baseFileName = theFiles(k).name;
    fullfilename = fullfile(theFiles(k).folder,baseFileName)
    fprintf(1,fullfilename);
    Test= dlmread(fullfilename,',',1,2)
    theMeans = mean(Test,1)
    Analysis1(:,k) = theMeans'
end

i also tried to save the file one by one, then it worked. just i dont know how to save them all automatically. any help? thank you.

f=fullfile('D:\','Data','MDA231','MDA231 Mito cell1_Statistics','MDA231 Mito cell1_Area.csv')
f =
    'D:\Data\MDA231\MDA231 Mito cell9_Statistics\MDA231 Mito cell9_Area.csv'
>> copyfile(f, destdir)
