Re: [Discuss-gnuradio] To store input data

[Jeff Long]

You can limit the number of samples using Head.

To see the results, add File Sinks wherever you want to save samples, 
and use an external program to view, or use something like the QT Vector 
Sync in the flowgraph if it works for your case.

If you are saving to a file, you do not need a Throttle, but if you're 
using one of the Instrumentation sinks, leave it in.

You may want to turn off "repeat" in the File Source if you only want to 
see the contents of the file once. File Source has an open() method that 
can be used (from Python) to open a new file, which might help.

As Marcus said, the more you say about what you're actually trying to 
do, the better people can help you.
