[Discuss-gnuradio] Single step a stream

Hi,

 

Is it possible to single step a flow graph?

 

I have a recorded stream of FSK modulated data with about 25 bursts of messages.
When this is later decoded I do not get 100% detection, about 4 of 25 bursts fails.

 

Now my thinking is can I play this burst by burst and see what is wrong.
So my plan was to stop the scheduler after each burst.
Can I control (stop) the scheduler when a 'tag' is detected and restart it with a GUI button.

 

Block,Python,C++ dosen't matter...
