Finds data "tails" near data gaps and selects keys that are members of the tail so you can delete or filter them.

Often gaps are preceded or followed by erratic data segments. As an optical capture system is losing track or re-acquiring a marker, there can be noisy elements on the edges of gaps called tails. The findTails command is designed to identify these unwanted bits of data so that you may remove them.

The threshold setting is used to adjust the number of keys selected. The useful range for threshold values is approximately 1-5; 1 selects a lot, and 5 selects very little. After finding tails, the most likely operation is to either filter or cut the select keys.
