The files in the scandata directory are what Spooky2 generates and then analyzes to provide you with a list of frequencies.
They are there for advanced users who wish to mine the data after the fact, but have no further value to Spooky2 after the result list has been returned.
There is no way to re-analyze them from within Spooky2 and you can not load them into the software. To try and do so will throw an error.
