File Sink block dumps lot of data in a file, and to analyze that I have  
to  
run this code snippet

\*import scipy  
f = scipy.fromfile(open(“your\_file\_name.txt”), dtype=scipy.float32)  
\*\*print f

- 

Is there any ready file\_read block in gunradio companion that I can use?  
Can I make a new custom block for same?

Thanks,  
Manoj

Try the File Source block.

Thanks for prompt reply,

I used file source block → vector sink

and then dumping the data in vector\_sink by editing top\_block.py as  
mentioned in  
[http://lists.gnu.org/archive/html/discuss-gnuradio/2012-08/msg00120.html](http://lists.gnu.org/archive/html/discuss-gnuradio/2012-08/msg00120.html)

1. The result ( vector\_sink.data() ) is a blank tuple
2. I’m expecting a single block which will abstract all these things so  
that I can directly read data from file\_sink

Is this possible or already done?

Thanks,  
Manoj
