Well, the lost of efficiantcy is huge. I need to compute the distance 
several time on data base that count 1000 or even 10 000 subjects. 10 
000^2 cost a lot in term of time, whereas 10 000 does not.

A solution would be to re-write DAISY and adapt it. But since I do not 
know fortran, I prefers first to ask if someone already did it...
