Files are stored in binary format. You need to open it as such. There
are some utilities that are in gr-utils/src/python that can be used
for quick plotting (gr_plot_*.py). They use the Scipy fromfile command
to read the samples and plot them with Matplotlib, which you can use
to do your own work.

In the ofdm examples directory, there is a file gr_plot_ofdm.py that
will plot the output of --log in a way that we've found useful. You'll
need Scipy and Matplotlib installed.
