Errors running script from command window MATLAB but not from run icon

Question

I have a function file which contains a GUI.

Whenever I run (compile) the file using the green run logo in MATLAB it successfully builds. Whenever I try to run it from the command window i.e: run(MyFile);I get this error but the file still builds correctly:

??? Error using ==> fileparts at 31
Input must be a row vector of characters.

Error in ==> run at 25
[p,s,ext] = fileparts(script);

I'm not getting the error when I hit 'run' in the text editor.

Thoughts?

31 error(message('MATLAB:fileparts:MustBeChar')); Was what I got when I typed: dbstop if error; run(MyFile); in the command window — loco

If matlab stops at the error, check what script is. Should be some file path (char) — Daniel

What do you mean by check what script is? Sorry, new to MATLAB. Where would I look? — loco

It should work this way:

runtmp = fullfile('foldername','filename.m');
run(runtmp);

notice that the 'run' command executes scripts not currently on the MATLAB path. However, you should use cd or addpath to navigate to or to add the appropriate folder, making a script executable by entering its name alone. The other point is run changes to the folder that contains the script, executes it, and resets back to the original folder. If the script itself changes folders, then run does not revert to the original folder, unless scriptname changes to the folder in which this script resides.
