Hi Sam,
The bbr files can be loaded back into Spike. If you press the play button on the sweep recording toolbar and select the bbr file, the software will sequentially play back the sweeps recorded in the file. You also have access to all sweep measurements when playing the file back through Spike.
You can also parse the file programmatically. I am attaching a file which shows how one would parse the bbr file in C. I would imagine it would be very easy to adapt this to Python. The format is very basic.
Let me know if you have further questions.
Regards,
A.J.
