Error using uiopen (line 167)

Hello,

I recently installed R2013b. Ever since I get the following error (see image). This happens whichever way I try to open the file (while matlab is off, within matlab, even typing edit won't work). Another thing I tried, I opened a script with notepadc++, copy-pasted to a new script in matlab, everything runs properly, save it, close it, reopen it and still get the error. Do you have any clue how can I get rid of this nuisance?

Thank you

I reinstalled the program but the error is still there

Do you have a space in your m-file's name? Can you paste line 167 here or attach your m and fig files?

[Ioannis]

Hi Image Analyst. Thank you. No, I do not have a space in any of my m-files names. These are all scripts I created and use for months now without a problem, on a R2012b version. Here is line 167

open(fn);

which is part of an inner if else condition. I have also attached a sample script.

Don't use open() to run another m-file. Just put its name on a line by itself, with the necessary input arguments of course.

Thanks, that's what I do now. I basically reinstalled it and still get the error but at least it works opening files by typing ''edit'' now so I can do my job.

If you want more advice, please give your new line 167 that shows how you are doing it now and still getting a warning/error.

Hello Yiannis,

I had the same Problem that is shown by the Error-Dialog. The error affected both, the open('...') command as well as the double-click uiopen(). The problem was caused by an *.slx file in the current working directory. The file's name was open.slx and shadowed the internal open-function open() and as it is used as a subroutine of uiopen (guess so) also caused problems with uiopen(). Deleting the file and restarting Matlab (do not know why this is necessary, but deleting only did not help) fixed the problem.

Best regards, Philipp

What are .SLX files? Are they executable files like m-files and p-files?

[Walter Roberson]

.slx files are Simulink models. They are considered executable. They are #3 in the priority list; see https://www.mathworks.com/help/matlab/matlab_prog/function-precedence-order.html

Ehmm, this might be my fault of describing the problem in the first place. You see, I was opening my m-files by double clicking the relative file I wanted to work on. uiopen is apparently used by matlab to open the file for me and this is what was giving me the error once I shifted to R2013b. It would tell me that the file is not there, which is not the case. After I cleaned and reinstalled it I still get the same error when I double click on an file but at least I can type 'edit myfile' which works fine. I have no idea how to fix this though. Sorry for the initial explanation.
