I have a bunch of files in a folder, with names that look like this:
squad1_1910_St4_Se8
squad1_1910_St2_Se3
squad1_1910_St1_Se6
squad1_1910_St4_Se5
I have a code that automatically updates the file using regexprep, amongst other things. right now, the code chooses the file with user input, for instances:
root = 'E:\MATLAB';
user_input_squad = input('please enter squad number: ', 's');
user_input_experiment = input('please enter experiment name: ', 's');
user_input_stage = input('please enter stage: ', 's');
user_input_session = input('Please enter session: ', 's');
file = fullfile(root, sprintf('squad%s_1910_EXP%s_St1_Se%s', user_input_squad, user_input_experiment, user_input_session));
Is there a way for matlab to pull the last file added, without the need for user input? something that sorts the directory by date, and chooses the first one?
this would have to be for a bunch of files, as they change periodically. for instance, there would be 2 files named
squad1_1910_St4_Se8
the squad number is the only chnage to the name. so if a user inputs squad 2, is there a way to automatically pick only the latest squad 2 file, without touching the others?

You can use dir() to get the file date/time stamps.
folder = pwd; % Whatever folder you want.
filePattern = fullfile(folder, '**\*.txt')
dirListing = dir(filePattern)
fileDates = [dirListing.datenum]
% Sort in descending order (most recent, latest date as item #1)
[sortedDates, sortOrder] = sort(fileDates, 'Descend')
% Sort files in that order.
dirListing = dirListing(sortOrder); % Rearrange using the new sort order.
fileNames = {dirListing.name}
% Let user know the most recent file.
message = sprintf('The most recent file is %s.\nIt has a date time stamp of %s', ...
fileNames{1}, datestr(dirListing(1).datenum))
fprintf('%s\n', message);
uiwait(helpdlg(message));
Let me know if it works for you (after obvious modifications of course).

If you already have identified the most recent file's name, then you can simply see if that filename contains 'squad1' by using contains():
if contains(mostRecentFileName, 'squad1', 'IgnoreCase', true)
% Then the most recent file contains the string 'squad1' in its name.
end
