for two datasets A & B
where records a are in dataset A and records b are in dataset B

Blast query a against target dataset B to obtain best hit b'
Blast query b' against target dataset A to obtain best hit a'

if a == a' then b' is the reciprocal best hit of a (rbh)
otherwise a and b' are not reciprocal best hits

this is done for all a in A.
(and possible for any b in B not a rbh of something in A)

sorry if this too abstract. but the question is not so specific.
