select event

Select data from the event lists.

Syntax: 

xsel > select event <event_sel>

Examples:

To select data from within a circular region centered on (X,Y)=(125,125) with a radius of 10.0.. 

xsel >  select event "Sqrt((X-125)\^2 + (Y-125)\^2) < 10.0"

Note that for region selection and timing selection, it is quicker to pass the criteria as filters to the extract command.
