Gonzalo Flores De La Parra > Electrónica en Comunicaciones > Universidad Autónoma Metropolitana > http://gnuradio.org/redmine/projects/gnuradio/wiki/FAQ#What-is-the-file-format-of-a-gr_file_sink Basically, you're writing a binary file, so a text reader won't know what to do with it (you could use emacs in hexl mode, though). There are a handful of plotting tools in the current releases of GNU Radio that you can use, named gr_plot_xxx (where xxx = float, int, iq, const, etc.). These use scipy.fromfile to read in the binary data. Tom
