Hi all:  
I have installed the gr\_specest toolbox successfully.And I use  
the gnuradio 3.7.5.But when I run the specest\_from\_file.py,error  
exists:

```
     File "/usr/local/bin/specest_from_file.py", line 142

```

SyntaxError: Non-ASCII character ‘\xce’ in file  
/usr/local/bin/specest\_from\_file.py on line 142, but no encoding  
declared; see [PEP 263 – Defining Python Source Code Encodings | peps.python.org](http://www.python.org/peps/pep-0263.html) for details

```
Can someone explain it to me?Also I can't find the file 4cos.dat as 

```

That’s actually a bug; I’ve submitted a pull request. You can locally  
use my change by doing  
git pull [GitHub - marcusmueller/gr-specest: A module adding spectral estimation routines to GNU Radio.](https://github.com/marcusmueller/gr-specest.git) fix\_encoding

Sorry, my bad. Fixed my fix, should be clear now. Maybe you have to pull  
–force, sorry about that.

I guess that is just an invocation example, so there is no 4cos.dat;  
you should supply your own signal file.

In fact, it’s a bug in GNU Radio.

See: [http://gnuradio.org/redmine/issues/707](http://gnuradio.org/redmine/issues/707)  
And: [Source code encoding not properly declared · Issue #9 · kit-cel/gr-specest · GitHub](https://github.com/kit-cel/gr-specest/issues/9)

Hi Marcus:  
Thank you so much for your kindly reply.It now can  
run.And I want to know where can I find the docuement 4cos.dat as some  
examples shows.  
Just like this:  
specest\_from\_file.py -M welch -S 4cos.dat  
4cos.dat: No such file or directory
