Problem with SegmentTool.

Dear all,

I have a problem (maybe small problem, but I can´t handle it) with SegmentTool. I downloaded zip here https://www.mathworks.com/matlabcentral/fileexchange/38484-segmenttool--an-interactive-gui-for-segmenting-images and I unzipped this folder. But when I write to the Command Window SegmentTool, so I see this error:

Undefined function 'audioread' for input arguments of type 'char'.

Error in SegmentTool (line 133)
[wav,freq] = audioread('notify.wav');

How do I resolve this? Thank you for your answers.

Veronika - which version of MATLAB are you using? According to audioread, this method was introduced in R2012b and so you may not have this function if using an earlier version of MATLAB. At the Command Line, type

 which audioread -all

to see if you have this function and

 ver

to determine your version of MATLAB.

[Veronika]

Yes, I have really old version (R2011b). So I don´t have audioread function. I try another version. Thank you for your answer.

Veronika, it appears you didn't see my solution below. Of course using a more modern version is better though.

Answer 2

[Image Analyst]

You must have a really old version. Try wavread() instead:

[wav,freq] = wavread('notify.wav');

[Veronika]

Yes, I have R2011b version. I tried, what you advised. Variables were loaded into the workspace and no error messages appeared. But I do not know how to proceed.

[Image Analyst]

What do you want to do with it? Geoff and I don't know. You didn't tell us. Why are you reading it in in the first place?

[Veronika]

I need to do segmentation area of the image and after that create FEM model from this area.

[Image Analyst]

What image? You know you're reading in a wav file, which is a sound file, don't you?

[Veronika]

That's what I'm not sure. I need to edit the image, so I downloaded SegmentTool. I don´t know why is there mistake about the audio (sound) file.

[Image Analyst]

Well evidently it tries to load and play a sound file. So either replace it with waveread() like I said, or just replace it with

beep();

or simply comment it out. Let me know if that solves the problem.

[Geoff Hayes]

Veronika - for some reason, the author of the SegmentTool has included a wave file for notifications (a message indicating that something is happening). If playing this sound is still causing you a problem, then I would remove the three or four lines corresponding to it from the code.

I see that you have started a new question at http://www.mathworks.com/matlabcentral/answers/301959-how-to-start-segmenttool-and-import-image which may explain more clearly what problems you are having with this code.

[Veronika]

Image Analyst I can´t comment it out or replace it, because it reports: "Access denied".

Geoff Hayes I can´t remove lines, because of "Access denied". My new question relates a newer version (R2016a).

[Image Analyst]

Either you have it open in another program, or you have it saved in a place where you can't edit it, like under the Program Files folder somewhere. Move it to a folder where you do have permission.

[Veronika]

Ok, so I commented out this two lines:

[wav,freq] = audioread('notify.wav');
notification = audioplayer(wav,freq);

Is it enough? Application is started in order, but some buttons and sliders don´t react and error appeares. So far it does not affect the function of the application.

So far, thank you very much.
