Abhijeet,
If you just want to read the contents of the files then you can read them using the scripts provided in */gnuradio/gnuradio-core/src/utils/.
read_char_binary, read_complex_binary etc will suffice most of your needs. I normally addpath('/opt/gnuradio/gnuradio-core/src/utils') in MATLAB and play around with the collected raw data.
Hope this helps.

Hi,
Getting the data into Octave is quite easy
fid=fopen('file.dat');
readsize=1000; % e.g. if you want to read 1000 samples
ir=1:2:2*readsize-1;
ii=2:2:2*readsize;
[val, count] = fread (fid, readsize*2, 'float'); % times 2 for reading
I/Q data
s=complex(val(ir),-val(ii)); % put the data into a complex vector
%
% ... some processing here
%
fclose(fid);

Thomas

Hi,
I am new to gnu radio and I have a dat file (complex or float)
captured from file sink which was directly connected USRP.
Can anyone help me with how to see the dat file in octave or any
other similar software. Is there any other method to see the content of
dat file as i need that data for processing.
Thanks and Regards,
Abhijeet.
