| Automatic block width
The default automatic block size is equivalent to 13 samples or 12 sample intervals (e.g., 60 seconds with a 5-second sample interval). Any other block size can be selected, as long as it contains more than 2 samples and less than 1/4 of the file duration. In this example, a 5-minute block duration (300 seconds) has been selected.
Return to the standard two-click selection method with the 'Normal block selection' button.
