Hello,

I have tried opening the flow graph for coverting .bin file (data  
captured via sdr rtl) to .cfile for analysis. I downloaded the file from  
the link below  
[http://sdr.osmocom.org/trac/attachment/wiki/rtl-sdr/rtl2832-cfile.grc](http://sdr.osmocom.org/trac/attachment/wiki/rtl-sdr/rtl2832-cfile.grc)

However, I am unable to get it working on GRC 3.7.2.1

I get a long list of error messages (given below) when I just try to  
open the file

I am using Ubuntu v14.04.1.

I am really stuck at this point as the rest of my analysis depend on  
this.

I would be really grateful for any help.
