System Identification toolbox error

Hi there,

I am a beginner to MATLAB System Identification toolbox. I started with MATLAB example "Identify Linear Models Using System Identification App"which is

%*** MATLAB code***
load dryer2
systemIdentification
%*** ***

I am getting the following error:

Warning: The EraseMode property is no longer supported and will error in a future release. 
> In waitbar (line 269)
  In ident (line 55)
  In systemIdentification (line 36)
  In main_example1 (line 10) 
Warning: The EraseMode property is no longer supported and will error in a future release.

Did you happen to try to run the code after having worked with App Designer ?

I don't quite understand what you mean but I tried System Identification App but I am also getting the same error. Thanks for your help!

Do not worry ab out the warnings about EraseMode .

Please give the command

delete('all')

to close all figures, and then try again.

Which MATLAB release are you using?

[turki haj mohamad]

I tried that and I am still getting the same error.

I had 2018a and it gave the same error and I downloaded 2018b last night and I'm getting the same error.

Try

restoredefaultpath

and then running. Perhaps you have an add-on or third-party toolbox that has a routine that is conflicting with a MATLAB routine of the same name.

Bingo! it worked. Thank you very much.
