Hello, I'm working on a GUI where I'm playing .wav files to people. I want the listeners to be able to type the words they hear into an edit box and then push a button to have matlab save that response in a .txt (or .dat) file before moving on to the next .wav file.
the goal is to have a txt file at the end with all 50 or so responses.
function pushbutton1_Callback(hObject, eventdata, handles)
s= get(handles.edit1, 'String')
output_s = fopen('newtest.dat','w');
formatSpec = '%s';
fprintf(output_s,formatSpec,s);
end
I'm fairly new to MatLab coding, so any specific help would be great. Thanks!

Hi Shae,
I understand that you would like to save user responses from all the edit boxes into a single text file.
fprintf function only accepts numeric or character array as data to be written to a text file. In your case, the variable 's' is a cell array. You can either use the cell2mat function to convert the cell array to character array or simply replace 's' by 's{:}'.
fprintf(output_s,formatSpec,s{:});
Moreover, since you want to append multiple responses to a single text file, the permission argument for fopen function should be either 'a', 'a+','at' or 'at+'. This allows you to append data to the file without discarding its existing contents.
So your final code should look something like this
function pushbutton1_Callback(hObject, eventdata, handles)
s = get(handles.edit1, 'String');
output_s = fopen('newtest.txt','a'); % permission can also be set to at,a+ or at+
formatSpec = '%s';
fprintf(output_s,formatSpec,s{:});
I hope this piece of information helps you to resolve your issue

This code woks but it will not work if it stays with only one s = get(handles.edit1, 'String');
so you will add get([handles.edit1, handles.edit2], 'String');
and the complete code:
s = get([handles.edit1, handles.edit2], 'String');
output_s = fopen('newtest.txt','a'); % permission can also be set to at,a+ or at+
formatSpec = '%s';
fprintf(output_s,formatSpec,s{:});
