I have a string, where I use strrep to replace a variable witha user input:

string = ('Today, I ate some (x)')
user_input = input('Enter your food: ', 's');
newstring = strrep('string', '(x)', user_input);

I want to use an editable textbox to get user_input. How would I do that?

My full script will have 3 editable textboxes, and 2 popups.

the popups will be changing a directory path, like I do here with sprintf:

user_input_food = input('enter food: ');
user_input_amount = input('enter amount: ');
root = 'C:\Users\Administrator';
% full path should look like C:\Users\Administrator\food\amount\food_amount.txt
filepath = fullfile(root, sprintf('food%s', user_input_food,), user_input_amount, sprintf('food%s_amount%s.txt', user_input_food, user_input_amount);

how do I get a popup menu to populate the user_input_experiment/user_input_squad variables?

user_input_food = handles.food_textbox.String;        %assuming you named the edit uicontrol food_textbox
user_input_amount = handles.amount_textbox.String;
filepath = fullfile(root, sprintf('food%s', user_input_food), user_input_amount, sprintf('food%s_amount%s.txt', user_input_food, user_input_amount));

how do I get a popup menu to populate the user_input_experiment/user_input_squad variables?

If it is to be done according to computed content, then set the String property of the popup to a cell array of character vectors, one per line. Access the Value property to determine the index of which was selected. If you want to know the selected text, then for example,

experiment_choices = handles.experiment_popup.String;
user_choice = handles.experiment_popup.Value;
user_input_experiment = experiment_choices{user_choice};

I did that, and immediately got the dialog box telling me that the file does not exist, with the placeholder values I set in the GUI. When commenting out that line, I got the same error as last time. I am appending the full code, to clarify.

function varargout = Macro_updating_OutputFcn(hObject, eventdata, handles)
% Initialize by cleaning up
%add complete paths to every template file you will be using, if not, MATLAB cannot find the appropriate files
addpath('C:\Users\Administrator\Dropbox (********)\******** Team Folder\Matlab\RFID chip reader\EXPT1\1',...
    'C:\Users\Administrator\Dropbox (********)\******** Team Folder\Matlab\RFID chip reader\EXPT1\2',...
    'C:\Users\Administrator\Dropbox (********)\******** Team Folder\Matlab\RFID chip reader\EXPT1\3',...
    'C:\Users\Administrator\Dropbox (********)\******** Team Folder\Matlab\RFID chip reader\EXPT1\4',...
    'C:\Users\Administrator\Dropbox (********)\******** Team Folder\Matlab\RFID chip reader\EXPT2\1',...
    'C:\Users\Administrator\Dropbox (********)\******** Team Folder\Matlab\RFID chip reader\EXPT2\2',...
    'C:\Users\Administrator\Dropbox (********)\******** Team Folder\Matlab\RFID chip reader\EXPT2\3',...
    'C:\Users\Administrator\Dropbox (********)\******** Team Folder\Matlab\RFID chip reader\EXPT2\4');
root = 'C:\Users\Administrator\Dropbox (********)\******** Team Folder\Matlab\RFID chip reader';
%ensure you are entering just the number, and nothing else, including
%spaces before or after, as this will throw an error.
experiment_choices = handles.popupmenu1.String;
user_choice = handles.popupmenu1.Value;
user_input_exp = experiment_choices{user_choice};
user_input_squad = handles.edit1.String;
filepath = fullfile(root, sprintf('EXPT%s', user_input_exp), user_input_squad, sprintf('EXP%s_SQ%s_Template.txt', user_input_exp, user_input_squad));
if isempty(user_input_exp)|| isempty(user_input_squad)
    return
end
if ~exist(filepath, 'file')
    errordlg(sprintf('file location does not exist, "%s"', filepath), 'Error Dialog', 'modal')
    return
end
Mac_Templ = importdata(filepath);
user_input_stage = handles.edit2.String;
todaysMac = Mac_Templ;
todaysMac = strrep(todaysMac, '(m)', user_input_stage); %update stage with user input
user_input_session = handles.edit3.String;
todaysMac = strrep(todaysMac, '(n)', user_input_session); %update session with uyser input
user_input_list = handles.edit4.String;
todaysMac = strrep(todaysMac, '(x)', user_input_list); % update list with user input
todaysMac = string(todaysMac); 
todaysMac = compose(todaysMac); % There was an issue with the files, where
% the output would be in a single line. this fixes it, by using the escape
% characters located at the end of each line in the template (\n), compose
% basically reads those as a command, placing each box into a new line.
fid = fopen(fullfile('C:\Users\Administrator\Dropbox (********)\******** Team Folder\Matlab\RFID chip reader\Completed_Macros', sprintf('EXP_%s_SQ%s_completed.mac', user_input_exp, user_input_squad)), 'wt'); % Makes a new file in
%specified directory, with specified name and format at the end. saving a
%second file with the same name will overwrite older file.
fprintf(fid, '%s', todaysMac);
fclose(fid);
disp('Done');
% varargout  cell array for returning output args (see VARARGOUT);
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
% Get default command line output from handles structure
varargout{1} = handles.output;

That's what I thought you meant. Populating the handles and then only actually running the importdata() at the user's behest. I will definitely try that, and update you. Thanks for the help so far, I really appreciate it.

that works perfectly, thanks for the help. If you have time, I posted a new question for a connected project. thanks so much.
