The 'Start Recording' button will start recording data using the other settings in the window. The button will then change to 'Stop Recording'.
The 'File...' button will let the user choose a file name for data. The name of the file will be displayed in the text field next to the button. With a file chosen, data will be saved to the file as it's being generated.
It's possible to use this feature to pass data from CERT to another application. Create a fifo (using the mkfifo command from Mac OS X's command line), choose the fifo file with the 'File...' button. Another process will then need to start reading from the fifo to unblock. Then start recording as normal. If the receiving process blocks for any reason, it could cause CERT to freeze.
Not Tab Delimited. Every data field from each frame or image is labeled.

The 'Clear' button deletes any data in the Face/AU Data window.
The 'Save...' button lets you save any data in the Face/AU Data window to a file.
If no output file has been chosen then data will show up in the bottom section of the Face/AU window only after recording has been stopped. Data going to a file does not show up.
