Hi,

Please see the code below I used to extract the information from the folder. So the folder has 28 sub-folder with the name "Run 12-27-56.Adaptive PIV.6uqqm6yu", and so on. I want to plot on X-axis number of floder like 1,2,,3,4,5,6....28 and on y-axis corresponding file name (only the number part for example 12-27-56) which is a timestamp actually. Can you help, I am posting the code and result below.

Code:

close all; clear all; clc

%Location of the directory

Location = 'F:\3-PIV_Experimental_Data\Outlet_110\Data_LaserSheet_A\Data_Vector_Masked';

% Get a list of all files and folders in this folder.

files = dir(Location);

% Get a logical vector that tells which is a directory.

dirFlags = [files.isdir];

% Extract only those that are directories.

subFolders = files(dirFlags); % A structure with extra info.

% Get only the folder names into a cell array.

subFolderNames = {subFolders(3:end).name} % Start at 3 to skip . and ..

%Print folder names to command window.

for k = 1 : length(subFolderNames)

fprintf('Sub folder #%d = %s\n', k, subFolderNames{k});

end

Results:

Sub folder #1 = Run 12-27-56.Adaptive PIV.6uqqm6yu

Sub folder #2 = Run 12-28-48.Adaptive PIV.6uqqlrqv

Sub folder #3 = Run 12-29-46.Adaptive PIV.6uqqlgku

Sub folder #4 = Run 12-30-23.Adaptive PIV.6uqql4fz

Sub folder #5 = Run 12-31-15.Adaptive PIV.6uqqkre7

Sub folder #6 = Run 12-31-50.Adaptive PIV.6uqqkfgv

Sub folder #7 = Run 12-32-25.Adaptive PIV.6uqqk3d3

Sub folder #8 = Run 12-33-17.Adaptive PIV.6uqqjqh2

Sub folder #9 = Run 12-33-54.Adaptive PIV.6uqqjctq

Sub folder #10 = Run 12-34-27.Adaptive PIV.6uqqiyst

Sub folder #11 = Run 12-35-04.Adaptive PIV.6uqqip1p

Sub folder #12 = Run 12-36-17.Adaptive PIV.6uqqidrr

Sub folder #13 = Run 12-36-47.Adaptive PIV.6uqqi25r

Sub folder #14 = Run 12-37-21.Adaptive PIV.6uqqhnwu

Sub folder #15 = Run 12-37-58.Adaptive PIV.6uqqhcsl

Sub folder #16 = Run 12-38-37.Adaptive PIV.6uqqh0on

Sub folder #17 = Run 12-39-27.Adaptive PIV.6uqqgp8m

Sub folder #18 = Run 12-40-01.Adaptive PIV.6uqqgdqt

Sub folder #19 = Run 12-40-36.Adaptive PIV.6uqqg1kn

Sub folder #20 = Run 12-41-11.Adaptive PIV.6uqqfpie

Sub folder #21 = Run 12-42-03.Adaptive PIV.6uqqfco7

Sub folder #22 = Run 12-43-07.Adaptive PIV.6uqqf0sv

Sub folder #23 = Run 12-43-59.Adaptive PIV.6uqqenyl

Sub folder #24 = Run 12-44-36.Adaptive PIV.6uqqdwdb

Sub folder #25 = Run 12-45-16.Adaptive PIV.6uqqdkcu

Sub folder #26 = Run 12-45-51.Adaptive PIV.6uqqd6wt

I would suggest converting the extracted timestamps to durations. Then you can just plot it. The x value will be the index number of the timestamp (1, 2, 3, ...) and the y value will be the time, formatted as a time.

It takes a little manipulation to get things formatted correctly, but not a lot of code.

subFolderNames(1) = "Run 12-27-56.Adaptive PIV.6uqqm6yu";

subFolderNames(2) = "Run 12-28-48.Adaptive PIV.6uqqlrqv";

subFolderNames(3) = "Run 12-29-46.Adaptive PIV.6uqqlgku";

subFolderNames(4) = "Run 12-30-23.Adaptive PIV.6uqql4fz";

subFolderNames(5) = "Run 12-31-15.Adaptive PIV.6uqqkre7";

subFolderNames(6) = "Run 12-31-50.Adaptive PIV.6uqqkfgv";

subFolderNames(7) = "Run 12-32-25.Adaptive PIV.6uqqk3d3";

subFolderNames(8) = "Run 12-33-17.Adaptive PIV.6uqqjqh2";

subFolderNames(9) = "Run 12-33-54.Adaptive PIV.6uqqjctq";

subFolderNames(10) = "Run 12-34-27.Adaptive PIV.6uqqiyst";

subFolderNames(11) = "Run 12-35-04.Adaptive PIV.6uqqip1p";

subFolderNames(12) = "Run 12-36-17.Adaptive PIV.6uqqidrr";

subFolderNames(13) = "Run 12-36-47.Adaptive PIV.6uqqi25r";

subFolderNames(14) = "Run 12-37-21.Adaptive PIV.6uqqhnwu";

subFolderNames(15) = "Run 12-37-58.Adaptive PIV.6uqqhcsl";

subFolderNames(16) = "Run 12-38-37.Adaptive PIV.6uqqh0on";

subFolderNames(17) = "Run 12-39-27.Adaptive PIV.6uqqgp8m";

subFolderNames(18) = "Run 12-40-01.Adaptive PIV.6uqqgdqt";

subFolderNames(19) = "Run 12-40-36.Adaptive PIV.6uqqg1kn";

subFolderNames(20) = "Run 12-41-11.Adaptive PIV.6uqqfpie";

subFolderNames(21) = "Run 12-42-03.Adaptive PIV.6uqqfco7";

subFolderNames(22) = "Run 12-43-07.Adaptive PIV.6uqqf0sv";

subFolderNames(23) = "Run 12-43-59.Adaptive PIV.6uqqenyl";

subFolderNames(24) = "Run 12-44-36.Adaptive PIV.6uqqdwdb";

subFolderNames(25) = "Run 12-45-16.Adaptive PIV.6uqqdkcu";

subFolderNames(26) = "Run 12-45-51.Adaptive PIV.6uqqd6wt";

dates = extractBetween(subFolderNames,"Run ",".");

dates = replace(dates,'-',':');

dates = duration(dates,"InputFormat","hh:mm:ss")

dates = 1×26 duration array

12:27:56 12:28:48 12:29:46 12:30:23 12:31:15 12:31:50 12:32:25 12:33:17 12:33:54 12:34:27 12:35:04 12:36:17 12:36:47 12:37:21 12:37:58 12:38:37 12:39:27 12:40:01 12:40:36 12:41:11 12:42:03 12:43:07 12:43:59 12:44:36 12:45:16 12:45:51

plot(dates)

I used the help documentaton for MATLAB. Go there and then just search for each of the functions I used.

Here is something you can try:

close all; clear all; clc
%Location of the directory
Location = 'F:\3-PIV_Experimental_Data\Outlet_110\Data_LaserSheet_A\Data_Vector_Masked';
% Get a list of all files and folders in this folder.
files = dir(Location);
% Get a logical vector that tells which is a directory.
dirFlags = [files.isdir];
% Extract only those that are directories.
subFolders = files(dirFlags); % A structure with extra info.
% Get only the folder names into a cell array.
subFolderNames = {subFolders(3:end).name} % Start at 3 to skip . and ..
timeStamps = regexp(subFolderNames,'(\d+)-(\d+)-(\d+)','tokens');
timeStamps = vertcat(timeStamps{:});
timeStamps = cellfun(@str2double,vertcat(timeStamps{:}));
date_of_year = [2022 1 14];
y = datetime( ...
    date_of_year(1),date_of_year(2),date_of_year(3), ...
    timeStamps(:,1),timeStamps(:,2),timeStamps(:,3));
plot(1:numel(subFolderNames),y);
