	Dear Marc,

I indeed do not see the explanation in the manual, but I did some testing and I 
understand that :
- Identity and Similarity are computed by dividing by the total length of the 
alignment
- Longest_Identity and Longest_Similarity are computed by dividing by the number 
of aligned positions (= total length of the alignment - number of indels)
- Shortest_Identity and Shortest_Similarity are computed by dividing by the 
length of the longest sequence

	Regards,
