a
6/7 programs implemented in RDP4 identified putative recombination event (see Section 2).
b
Events identified by 7/7 programs implemented in RDP4 or events where more than one environmental isolate showed the same event (see Section 2).
c
Strongly supported events (row 3) divided by number of sequences analyzed (row 1).
d
